Abstract
A plurality of thermal power generation plants 100 are provided with a communication terminal 200 and a function of controlling respectively a boiler control unit 110, a turbine control unit 120 and an auxiliary machine sequence control unit 130 based on an operation signal inputted via the communication terminal 200. A remote control center 10 which is connected to the communication terminal 200 via the Internet 300, accesses the control units and remotely controls operating states including starting and stopping of the concerned thermal power generation plant 100.
Claims2
A power generation plant remote control and operation method for remote controlling a plurality of power generation plants, comprising:
- a centralized monitoring device which is connected to the plurality of power generation plants via communication lines so as to permit mutual communication and which performs centralized monitoring of operation states of the plurality of power generation plants;
- and
- said centralized monitoring device includes a-plurality of start and stop control devices for remote controlling start and stop operation of the plurality of power generation plants and wherein a number of said start and stop control devices corresponds to the number of the plurality of power generation plants,
- wherein for starting or stopping each of the plurality of power generation plants, each of the plurality of start and stop control devices is provided with a processing program for each corresponding one of the power generation plants intended to be started or stopped, and each of the plurality of start and stop control devices performs an operation control for starting or stopping according to the processing program in which a control and operation sequence for starting or stopping is predetermined.
