BHEL has commissioned its first indigenously developed phase-shifting transformer at Kothagudem Thermal Power Station in Telangana.
BHEL sees this as a major development, opening up a new line of business. Such transformers fit well into modern transmission networks and smart grids. The new generation transformer will be used to control and improve power flow between 400kV and 220kV networks in either direction by shifting the phase as the system requires.
Reposing faith in BHEL’s capability to introduce new technology products, Telangana State Power Generation Corporation (TSPGCL) — formerly, AP Genco — had placed an order with BHEL for the country’s first phase shifting transformer, that improves transmission efficiency.
According to a statement, the BHEL’s Transmission Business Group and Corporate BHEL have carried out system studies on substation design. These transformers are manufactured at its BHEL Bhopal unit.
Capacity While BHEL has the overall capacity to make power transformers of 45,000 MVA (mega volt ampere) per annum, the Bhopal plant has the capacity to make 30,000 MVA of this. Being the largest manufacturer of transformers in India, BHEL has supplied more than 4,000 transformers, aggregating over 3,00,000 MVA in cumulative capacity, for transmission and distribution networks.
Apart from supplies to State Electricity Boards, NTPC and Power Grid Corporation, it has exported transformers to over 20 countries.
