System for controlling power generating plant having a plurality of units in accordance with distributed computer system

Claim 1

A power generating plant control apparatus, comprising: a) central supervisory control means for carrying out supervisory control of the operating states of individual generating units constituting a power generating plant by giving instructions necessary for operating said individual generating units in accordance with the usage of an electrical system; b) a plurality of memory means provided in each of said individual generating units for storing data necessary to operate said individual generating units; c) transmission means provided between said central supervisory control means and said plurality of memory means for transmitting said instructions and said data necessary for operating said individual generating units; and d) a plurality of unit control means for collectively operating and controlling said plurality of generating units to control a plurality of operation end groups which are respectively unified to each related operation by using a control logic and applying dedicated operations to said operation end groups, individual unit control means of said plurality of unit control means comprising a storage portion for storing said control logic with a predetermined number of patterns of every individual one of said operation end groups, and a calculation portion for independently selecting said control logic of one of said patterns for each of said operation end groups from said patterns stored in said storage portion on the basis of said instructions supplied from said central supervisory control means through said transmission means, wherein said central supervisory control means, said transmission means, and said plurality of memory means and said plurality of unit control means of said individual generating units, are organically combined with each other in the manner that: i) said instructions from said central supervisory control means are supplied to an individual memory means of said plurality of memory means through said transmission means; ii) said data stored in said individual memory means are read out from said central supervisory control means through said transmission means; iii) said individual unit control means processes and executes the control logic of said instructions from said central supervisory control means; and iv) a monitor display provided in said central supervisory control means displays information related to processing and execution of said individual unit control means.
