Cummins Power Generation awarded the highest recognition from the China data center industry


 

Cummins Power Generation (CPG) has been honored for its first PowerBlocTM project. The China Engineering Construction Standardization Association, China’s most prominent organization defining data center-related industrial standards, awarded CPG as part of the Data Center Scientific and Technological Achievement Awards. The winner’s list was officially announced during the 9th Data Center Standards Summit. 

Launched in May 2021, PowerBloc was designed by the CPG China team and is manufactured in the CPG China plant in Wuhan, a city in central China. PowerBloc integrates diesel units (power systems), water tanks (cooling systems), fuel tanks (fuel systems), silencers (noise reduction systems), electrical switch cabinets (control systems), and fire protection systems in a highly integrated 40-foot standard container. The first of three PowerBloc gensets was installed at customer sites in September. The standard Installation Quality Assurance (IQA) test, 12-hour continuous load and one-hour overload tests were completed with the customer. The results not only validated 10 square meters of space saving compared to the traditional containerized unit, but demonstrated extra stable operation, low noise, low emission, and excellent performance of this innovative solution.

The PowerBloc project and its remarkable technical innovation has set a new benchmark for standby power in the data center field, especially the containerized area. The award represents the highest of its kind in the China data center industry.

“The concept, design, development and application of PowerBloc is just another vivid example of how our people live Cummins’ vision of innovating for our customers to power their success,” said Wang Lei, General Manager of CPG China. “The driver for this solution was to erase the pain point for our customers in the data center industry. The applause from the customers and the recognition from the industry gives us more confidence to further innovate value-added solutions for this industry.”

During the Summit, the China Data Center Committee also released a Data Center Containerized Diesel Generator Set Technical White Paper, which was co-authored with CPG. Cummins interpreted in detail the design elements, the problems existing in the application and the future development direction for containerized gensets serving as standby power systems.

CPG also utilized this opportunity to showcase its unique capabilities in providing power systems for data centers. The CPG booth attracted many participants from the design institutions that provide power system planning and design. The event was webcast and drew great attention from the public.

CPG has kept the leading position as the diesel genset provider in the China data center industry and continued its reputation as a lifecycle solution provider. Key customers include China Telecom, China Mobile, China Unicom, Alibaba, Tencent and ByteDance.

Home Generator Safety Checklist

Home Generator Safety Tips - Cummins

Follow these home generator safety tips when preparing your home and family for long-term power outages.

With a little more than one month left on the already tumultuous Atlantic hurricane season, not to mention the likelihood of severe winter storms on the horizon, now is the time for power outage preparation

Preparing for long term outages is important, and if you have already taken the step to ensure continuous emergency power by purchasing a generator, consider the steps you need to take to safely operate a backup home generator. 

The biggest risk of home generators is carbon monoxide (CO) gas. It is called “the silent killer” because it is odorless and colorless, meaning that most people inhaling it don’t even realize until it is too late. Symptoms of CO poisoning can look a lot like the flu, and in severe cases, it can cause permanent brain damage or death. CO can be especially dangerous for people who are sleeping or intoxicated.

Here are a few tips for keeping your family safe while operating a generator during your next power outage.

Portable Gas or Diesel Generators Safety Tips:

  1. Always follow manufacturer instructions when setting up a generator.
  2. Never use a generator inside your home or garage. They should be used outdoors in well-ventilated areas that are at least 20 feet away from any homes or dwellings.
  3. Look for any places air can enter the home near your unit and ensure that those are properly closed and sealed off. This includes windows or doors, air intakes, nearby dryer vents or crawl spaces.
  4. Reliable, approved, and operable battery powered CO detector alarms should be installed in proper locations on each floor in the home as specified by the manufacturer. 
  5. Give the generator a break that allows for any concentrated exhaust to clear away from the area. Open your windows and doors during this break to air out any concentration that may have collected in your home.
  6. Ensure that your generator is being appropriately maintained, including regular oil changes. 

Permanently Installed Gas or Diesel Generators Safety Tips:

  1. Install the generator outdoors only.  Work with a professional installer (link to https://cummins.tech/tj1e6z) to locate the generator away from windows, doors, and other openings to the house where exhaust gases will disperse away from the house or occupied areas.
  2. Install all parts of the generator enclosure at least 60 inches from any openings in walls of structures that may be occupied.  Examples of wall openings include, but are not limited to, operable windows, doors, dryer vents, fresh air intakes for heaters, etc.
  3. Look for any places air can enter the home near your unit and ensure that those are properly closed and sealed off. This includes, but not limited to, windows or doors, air intakes, nearby dryer vents or crawl spaces. Your generator must be located such that exhaust gases are not able to accumulate in an occupied area.
  4. Ensure that generators are used, maintained, and operated in accordance with manufacturer recommendations. If there is a concern that the installation standards have not been met, get an appropriate party, like the installer, out to inspect it.
  5. Give the generator a break that allows for any concentrated exhaust to clear away from the area. Open your windows and doors during this break to air out any concentration that may have collected in your home.
  6. Check the exhaust system for corrosion, obstruction, and leaks every time you start the generator and every eight hours when run continuously.
  7. Ensure that your generator is being appropriately maintained, including regular oil changes.
  8. Reliable, approved, and operable battery powered CO detector alarms should be installed in proper locations on each floor in the home as specified by the manufacturer.

Cummins home generators are extremely quiet, aesthetically pleasing and remotely accessible. If you have not yet taken the step to purchase a backup generator, consider scheduling a painless home assessment with your nearest Cummins dealer. In just a few minutes you can know exactly how little the ultimate peace of mind can cost.

Components of Microgrids

Microgrids are technology marvels. Check out the different components that come together under a microgrid.

Utility grids and microgrids have a lot in common. Both serve the same function—to provide electrical power to consumers. Both are subject to the same constraints—ensuring that electrical generation and electric load are equal at all times. Their components, however, are different. 

Microgrids are at a much smaller scale than utility grids and as a result include components that are accordingly scaled down. 

Here are the main components of a microgrid:

Electricity generation resources within microgrids

The beating heart of a microgrid consists of a set of electricity generation resources. Typical generation resources found in microgrids include diesel and/or natural gas generators, solar arrays and wind turbines.

The most basic microgrids are usually built around one or more diesel generators. When natural gas is available, gas generators are also among the options available. Older island microgrids, for example, are based on a small power plant consisting of a few diesel engines coupled to alternators. Generators are the default choice to power a microgrid because they can cover a wide range of loads and because they can be used as backup power. They start quickly, are responsive to changes in load, and can operate on a variety of fuels. 

Fuel cell technology is emerging as a valid option to provide on-demand power on microgrids. Fuel cells can run on natural gas, hydrogen and other less common fuels. Although their cost remains too high to be widely used, hydrogen fuel cells are seen as a potential source of small-scale CO2-free electricity.

Intermittent energy resources within microgrids

The cost of solar panels has become so low that, in some regions, their installation on homes and businesses is a no-brainer. University campuses, industrial facilities and others equipped with a microgrid can install solar arrays in large numbers, thus achieving significant savings on their energy bills. In fact, many build a microgrid specifically to be able to better integrate and take advantage of their solar resources. 

Energy storage within microgrids

Many homeowners sometimes choose to supplement their home photovoltaic installation with a battery pack. Likewise, many microgrid owners incorporate battery energy storage in their system. With the price of lithium-ion batteries at an all-time low, the benefits of adding an energy storage resource often justify the additional cost. 

For one, battery energy storage systems provide a service known as “time-shifting”. Time-shifting batteries collect extra electricity from an oversized solar system during the day, and then discharge the battery after the sun has set to meet overnight load demands. Similarly, batteries can be discharged at times when the solar array output does not match the load requirements such as short periods of peak demand. This allows the owner to maximize the use of intermittent resources.

Another benefit of battery systems is their ability to instantly respond to changes in electricity demand on the microgrid. Having a battery serve as standby capacity is often much more cost-effective than idling an extra generator 24/7 in case demand increases unexpectedly. Think of energy storage as the fat on the microgrid where energy is stored.

Load management within microgrids

Some microgrid owners have the option to actively manage electricity demand in the same way that they manage electricity generation. 

By default, when a large electric machine starts up somewhere on the microgrid, the generators supplying the microgrid need to quickly ramp up to meet the additional demand. Microgrids that actively manage demand have another option. They can decrease demand somewhere else on the microgrid, for example by switching off a building’s AC temporarily. The result is that demand and generation are again balanced out without increasing generation.

Control and communications within microgrids

Microgrids need a brain and a nervous system to operate safely and effectively, thus needing to possess sophisticated microgrid control systems

Wide-area utility grids serve millions of consumers and have a considerable amount of inertia, limiting the potential for fast, uncontrolled changes. Microgrids, in contrast, include fewer loads and resources and are more sensitive to variations in load and generation. Starting up several large electrical machines without the assurance that an equivalent amount of generation is available is a sure way to crash the microgrid. 

A microgrid’s control system typically includes multiple controllers and sensors distributed over its territory. A Supervisory Control and Data Acquisition (SCADA) system is also required to collect data and distribute instructions. 

If the SCADA system is the nervous system of the microgrid, then the energy management software is the brain; that software can be highly sophisticated. Artificial Intelligence (AI) and machine-learning features allow modern energy management software to learn to better anticipate load from the consumers on the microgrid and generation from renewable assets, to optimize the system to run in the most cost-effective way. Maximizing the use of renewable resources, minimizing fossil fuel costs and maintaining the reliability of the equipment and the microgrid, all while dispatching the load, is all taken care of by the energy management software, within the parameters specified by the owner of the microgrid.

Switchgears, inverters and other equipment

Finally, microgrids include other critical components such as electrical cables, circuit breakers, transformers and more. These components are the bones, muscles and blood vessels of a microgrid. They connect generation resources to consumers, and allow the microgrid’s control system to effect changes to the state of the microgrid.

Automatic transfer switches, for instance, isolate different generation assets to ensure that, for example, the AC inverter associated with a solar array does not feed electricity to a diesel generator. Inverters convert the DC power supplied by batteries or by solar panels to AC power that is adequately synchronized to other AC resources on the microgrid.
