Having sufficient power generation capacity is of little use if you cannot utilise that power efficiently. When a leading Indian steel-works was facing utilisation and control issues with its power plants, a retrofit solution based on DEIF AGC-4 controllers proved able to solve them.
Incorporated in 1997, Singhal Enterprises Pvt. Ltd. is an Indian steel-works with high ambitions for the future and a long-standing tradition for excellence. A series of major improvements in product quality, delivery, and customer satisfaction have resulted in strong growth for the company in the highly competitive steel market.
Steel production is a power-hungry undertaking, and Singhal Enterprises gets its manufacturing power from four steam-based CPPs (captive power plants) with a total generation capacity of 78MW on its site at Raigarh in the state of Chhattisgarh, India. However, the company was not satisfied with the old solution: Its existing controllers were old and unreliable, and Singhal Enterprises were not getting the manufacturer support they needed. Also, they wanted to integrate all of the CPP units on the same busbar to utilise the maximum combined power from the CPPs and improve power availability.
“The main problem was that we have power plants in different locations within two kilometres from one another,” explains Plant Manager Rajesh Rangu of Singhal Enterprises. “The old system was not able to coordinate these plants, and it was difficult to get full power”.
