The Cummins prime power systems are using their time-tested paralleling and load share controls to meet the local power needs in Al Wusta Governorate, Oman.
The Cummins prime power systems are using their time-tested paralleling and load share controls to meet the local power needs in Al Wusta Governorate, Oman.

In rural parts of Oman where there is no connection to the grid, villages rely entirely on the local power station, where Cummins generator sets run 24/7 in continuous operation. During winter, the load on the plant is minimal as there is less cooling required. However, with summer approaching, the load will increase and power requirement will thus be critical. 

With a need to upgrade the existing Dhafrat Power Station in Al Wusta Governorate, which covers the central region of Oman, the main contractor for the project, M/s. Global Chemical and Maintenance LLC, turned to Cummins and its authorized distributor, Universal Engineering Services (UES). UES has supplied around 120 Cummins generators to this customer, with current installed prime power capacity at 80 MW.

Cummins generators provide prime power for rural village in Oman.The Cummins prime power systems – 3 x C1400D5 units rated at 1 MW and 1 x C1100D5 unit rated at 500 kW – are using their time-tested paralleling and load share controls to meet the local power needs of the village without any interruption, providing 3.5 MW of total power output. The 1 MW units were engineered to order with medium-voltage alternators as the requirement called for an 11,000-volt unit, and work together in parallel, while the 500 kW unit is synchronized using a step-up transformer. The cooling system requirement meets harsh conditions of ambient temperature of 55°C and nearly 100% humidity, and noise levels of 85 dBA at 1 m are also met by the Cummins solution.

Cummins global footprint and local support gave the customer access to one of the most capable networks in the industry for their critical infrastructure upgrade – from product capability and market-competitive pricing through a robust supply chain and manufacturing process, to confidence in the technical support capability and aftermarket support. Built-in paralleling and load share controls were a key advantage compared to other generator suppliers, which usually offer a separate standalone paralleling and load share control.

Cummins-Powered Generator Sets Critical to Efforts to Add More Renewable Energy to the UK Grid

Cummins UKPR

Policymakers in the UK have prioritized decarbonization and higher penetration of renewable energy sources as important energy goals. With 66 million people and a GDP of 2.62 trillion dollars, the United Kingdom is the fifth largest economy in the world. Reducing carbon emissions, which come from burning coal and fossil fuels, is no small feat. 

UK Power Reserve (UKPR), part of the Singapore-based Sembcorp Industries group, wanted to provide an additional 500 megawatts of power to the UK national grid, but it was important for them to integrate their renewable energy sources with natural gas generators.

"Natural gas generators offer reliable power, which can be activated in distributed generation installations when renewable sources, like solar and wind, are not available because the sun is not shining, or the wind is not blowing," said Alex Savelli, Executive Director, Cummins Power Generation Business.

Today, UKPR has 26 plants, offering a combined 508 megawatts. This generating capacity is enough to power over a quarter of a million homes and meet over 1.4% of the UK’s peak demand for electricity.

Across the UK, 26 plants - not unlike the one pictured here - offer enough generating capacity to power over a quarter of a million homes. 

Across the 26 plants, Cummins installed a total of 254 of C2000N5C gas generator models along with transformers and switchgear in specially designed switch and control rooms in most of the sites. The industry-leading fast start capability offered by the C2000N5C models ensured each site can be on line when commanded by the National Grid in under 120 seconds, which was a critical requirement from UKPR.

UKPR’s gas-fired plants provide flexible, efficient, rapid-response power capacity to the UK energy market. These assets provide services to the market and National Grid at times of high demand, as well as offsetting the intermittency of renewable power sources such as wind and solar energy.  

"We’re proud to work alongside a company delivering low-cost, low-carbon solutions to the UK’s distributed energy mix," Savelli added.

Key Considerations and Benefits of Paralleling System Technology

Microprocessor electronics accomplish the necessary control and protective functions in a paralleling system that resulted in greater protection with fewer components, less interconnects, and a smaller footprint at Cox Enterprises data center in Phoenix, Arizona, USA.
Microprocessor electronics accomplish the necessary control and protective functions in a paralleling system that resulted in greater protection with fewer components, less interconnects, and a smaller footprint at Cox Enterprises data center in Phoenix, Arizona, USA.

Generator paralleling is a complex topic that has changed drastically from the operator in the early 1970s to today's autonomous microprocessor-based technology. In order for design engineers to design a comprehensive, reliable paralleling system, a good understanding of how paralleling is accomplished is needed. Paralleling encompasses synchronizing, de-energized bus arbitration, sync checks, load sharing, protection, metering, fault tolerance and paralleling with the grid and other power sources.

A primary advantage of paralleling is improved reliability: If one generator set fails, there are other generator sets to power the load. Enhanced performance is also a benefit, as a large generator bus capacity will act more like a utility, with fewer frequency and voltage variations during load steps. Paralleling allows for adding generator sets as power demand increases, and other generators are available to provide power while a single generator set is serviced.

Another advantage to explore is using distributed logic architecture vs. a Digital Master Control to enhance system reliability and eliminate single points of failure. This affects component specification and selection. System data such as load profile, voltage, amps and faults can be uploaded to the cloud and used for preventative maintenance and downtime reduction, which is a new technology in the power system industry.

For specifiers, a key consideration of a paralleled power system is to select the right equipment for the application to reduce overall cost and complexity.

Professionals seeking continuing education credits and resources to stay up to date with current codes, regulations and products can look to regularly-scheduled webinars and speaking engagements from Cummins. The topic of paralleling was presented earlier this year as a PowerHour webinar, and again during the Code Officials Association of Alabama’s Annual Education Conference. Want to learn more?

Digitization to Electrification: Five Macro Trends Transforming Electricity Markets

Digitization to Electrification: Five Macro Trends Transforming Electricity Markets

Trends ranging from digitization to electrification are driving an increase in the adoption of distributed generation over traditional centralized generation

We’re currently living in an era of choice when it comes to distributed generation. Or so says Satish Jayaram, General Manager of Distributed Generation Business at Cummins. 

“It has transformed how we access healthcare, revolutionized the telecom industry and reshaped how we think of transportation,” Jayaram said. “It’s also transforming the century-old electricity markets and offering customers the power of choice.” 

Today’s electricity markets look very different compared to the markets of just a few decades ago. To better understand this shift, we have compiled five main macro trends that are driving this transformation and how their outcomes create an environment favoring distributed generation.

De-regulation

Over the last two decades, electricity markets have increasingly de-regulated end to end: from generation to distribution, and directly to the end user. Today’s customers that live in fully de-regulated electricity markets enjoy the freedom of choosing their electricity supplier. Beyond offering customers the choice, de-regulation has also re-shaped the industry that once was dominated by vertically integrated utilities covering generation, transmission and retail. In de-regulated markets, many companies generate and sell electricity to a wholesale market, and retailers purchase electricity from the wholesale market to sell it to their customers. In summary, de-regulation results in a market where de-centralized grid co-exists with the centralized grid.

De-carbonization

Historically, fossil fuels, nuclear and hydro were the primary components of society’s energy supply mix. In recent years, increased focus on de-carbonization has resulted in wind and solar accounting for more than half of new power generation capacity additions. Moreover, it is expected that more than 50% of power generation will be renewable (including hydro) by the year 20351. This increasing focus on de-carbonization results in changes to energy supply mix. 

Digitization to ElectrificationElectrification

We use more electric vehicles (EVs) on our roads. We use more space cooling and appliances in our buildings. We use more hybrid boats on our seas. In summary, we are using more electricity and expected to increase electricity’s share in our total final energy consumption. This increased use of electrification results in changes to electricity demand patterns. 

Digitization

Electric power infrastructure is getting digitalized end-to-end. For instance, consumers experience this digitization in the form of smart meters. On the supply side, utilities take advantage of digitization through energy management systems utilizing economic or market-based constructs in managing the generation, consumption or flow of electric power. This increased digitization of electric power infrastructure results in monetization opportunities for customers. 

Technology

Recent technological advancements have reduced costs on generation and storage solutions. Both solar and wind generation are now near or at subsidy free levels. For storage, levelized-cost-of-storage for lithium-ion has decreased 80% in 10 years, making it economically viable for more applications and users. These cost reductions driven by advancing technologies result in increased customer adoption of Distributed Energy Resources (DERs).

Distributed generation solutions enable easier adoption of DERs (including renewables) to electricity infrastructure. DG solutions also help market participants manage changing electricity demand patterns. 

In summary, the outcomes of these five macro trends favor adoption of distributed generation over centralized generation. Customers, through Distributed Generation solutions, could more easily adopt DERs while also taking advantage of monetization opportunities. Market participants, through DG solutions, can integrate renewables to electricity infrastructure while managing changes in electricity demand patterns.
