I & C Concept
The Rousch Power Plant is equipped with Siemens state of the art distributed control system TXP. Control system provides all key plant information, trending, operating commands, alarms, plant history and protections at operators’ desks in control room enabling engineers and operators to control all plant operations from central control room. The operations management level is made in a redundant configuration with all key plant protections with 2 out of 3 logic to increase Plant reliability and minimize the risk of Plant tripping of false alarms.
The turbine generators supply power to national grid through 11 KV/500 KV unit transformers and gas- insulated switchgear to the 500-kV switchyard - an outdoor type substation with one and a half breaker method using SF6 circuit breakers. Two unit auxiliary transformers provide the plant auxiliary power supply from the generator leads to the 11-kV unit switchgear related to each gas turbine generator set. In the event of the grid failure, the 3000-kVA black-start diesel generator set provides power to the most essential equipment for the black-start of one gas turbine generator set.
