PURPOSE:To reduce the construction cost due to minimal application of one steam generator and one boiler controller by independently separating reheaters of a boiler according to the number of turbine generators so as to make independent load control of a plurality of the turbine generators. CONSTITUTION:Steam which is generated from a boiler 1 is supplied for a plurality of high pressure turbines 5 and 7 via respective steam regulation valves 3. Waste steam of the turbines 5 and 7 are reheated by reheaters 2 and then sent to intermediate pressure turbines 6 and 8, respectively. A plant target load setting unit 12 determines a target load and a load distribution setting unit 13 regulates the regulation valves 3, which control power generation of respective turbines to arbitrary loads. Since the operation of the boiler will be free from any restriction and one steam generator and one boiler controller are only required while a plurality in the ordinary case, the construction cost may be reduced. |
