1 generating insight | edition 4 Foreword Welcome to the 4th edition of Generating Insight. Like many companies, we appreciate the value of sharing our knowledge. It aligns with one of Cummins’ mission statements: “Partnering with our customers to make sure they succeed.” In this issue we have featured "Grid Codes - Compliance and Certification". With new legislation being adopted by more countries to help ensure continuous and stable power supplies as well as uniformity of transmission and distribution practices, Transmission System Operators and Distribution System Operators are applying...

2 generating insight | edition 4 UK Speaker of The House of Commons Visits Romania Facility The Right Honorable John Bercow, Speaker of the House of Commons and Member of UK Parliament visited Cummins Generator Technologies Romania earlier this year to celebrate continued British investment and manufacturing excellence in Romania. Cummins identified Craiova as the location to expand its larger generator production facilities during 2014 with an €11.5M investment in capacity as well as advanced manufacturing technologies and testing facilities. John Bercow MP was joined on this visit by...

3 generating insight | edition 4 Cummins Generator Technologies enhances its Customer Engineering support Cummins Generator Technologies' Applications Engineering team is determined to make sure that the generator you buy is right for you. The Applications team is an easy-accessible repository of product knowledge, operating experience and electrical engineering capability that can help ensure our products match your needs. However, for the Applications team to meet that challenge, many things need to be in place in order to make sure customer expectations are met each time, every time. In...

4 generating insight | edition 4 Equally important, to ensure these latest improvements reach and benefit customers, Cummins Generator Technologies’ Applications team has become even more closely aligned with the commercial organisation as members of key accounts teams. Together, they deliver focused applications guidance and product matching capability, ensuring a successful product delivery process to all customers. As a result of those organisational enhancements, customers will not only enjoy a quicker delivery of information and advice throughout the generator delivery process, but...

5 generating insight | edition 4 Commercial vehicle operators’ concerns about greener trucks and buses could be allayed with the development of integrated hybrid subsystem components. Putting a hybrid drive in a commercial vehicle is hardly ‘breaking news’…Europe’s truck and bus makers have been developing diesel/electric chassis for years, so today they’re no longer CV show ‘talking points’, but fullyavailable production-line models that have already been tried and tested by some of the biggest logistics, municipal and passenger transport fleets in Europe. Burning less fuel naturally means...

6 generating insight | edition 4 A typical Cummins CorePlus™ Motor Generator Battery Pack Cummins Power Electronics Cummins CorePlus™ Motor Generator The operating efficiency of the CorePlus generator, which has a maximum power of 90kW and a peak torque of 660Nm, is quoted as “greater than 95%." By adding its own CorePlus™ power electronics inverter and controls software to the motor generator, Cummins Generator Technologies has been able to optimise performance and efficiency. The operating efficiency of the CorePlus™ generator, which has a maximum power of 90kW and a peak torque of 660Nm,...

7 generating insight | edition 4 Grid Codes – Certification and Compliance An evaluation of generator set design implications and the certification process A Distributed Landscape By 2030, world electricity demand will have doubled since the turn of the century, if projections by the International Atomic Energy Agency are accurate. That power increase would have historically come from traditional sources of power generation such as fossil fuels and nuclear fission. But in today’s distributed power generation landscape a great deal of that additional demand will come from renewables and...

8 generating insight | edition 4 Under an FRT, the voltage at the Point of Common Coupling (PCC) drops to a very low value and the active load on the generating set drops proportionally. There is a chain of events now set in place. Firstly, the kinetic energy in the shaft tries to accelerate the unloaded generator toward a pole slip event. A generator designed with the correct levels of system inertia and synchronous reactance will limit the impact of this rotational step change and a pole slip will be avoided. However this stage of the FRT event will cause high levels of thermal and...
