Electric power plant general control system
First Claim
1. An electric power plant general control system comprising:
- a power generating unit having a plurality of auxiliaries, a part of the auxiliaries being operated based on an automation command outputted from a unit computer having a sequence function portion, and the remaining part of the auxiliaries being operated based on an operation command outputted from an operation board without a sequence function portion, the operation board disposed separately from the unit computer; and
a general automation computer connected with an upper system of the unit computer and making an operator command inputted thereinto from an interactive apparatus;
and being configured so as to output an operation signal into the unit computer through the general automation computer based on the operator command inputted from the interactive apparatus, wherein the electric power plant general control system is provided with a mock-up portion equivalent to the sequence function portion disposed on the side of the auxiliaries controlled by the automation command outputted from the unit computer, in a control system of the side of the auxiliaries controlled by the operation command from the operation board;
being configured to be able to output the operation signal outputted from the general automation computer into both the unit computer and the operation board; and
being configured to operate generally the auxiliaries of the power generating unit.

Abstract
An electric power plant general control system for controlling power generating units. A generating unit (GU2) can operate part of the auxiliaries based on an automation command outputted from a unit computer (UC2) having a sequence function portion. The generating unit operates the remaining part of the auxiliaries based on an operation command outputted from an operation board (OB2) without a sequence function portion, the operation board disposed separately from the unit computer. A general automation computer (GAC) is connected with an upper system of the unit computer, and an operator command is inputted from an interactive apparatus (I/F4). The general control system is provided with a mock-up portion (Moc) equivalent to the sequence function portion disposed on the side of the auxiliaries controlled by the automation command outputted from the unit computer. The operation signal from the general automation computer is outputted to the unit computer and the operation board.

3. An electric power plant general control system comprising:
-
a first power generating unit having a plurality of auxiliaries operated based on an automation command outputted from a unit computer;
an operation board outputting an operation command to the auxiliaries;
a second power generating unit having a plurality of auxiliaries excluded from automatic control and operated based on an operation command outputted from the operation board;
a general automation computer connected with an upper system of the unit computer and outputting an operation signal based on an operator command inputted from an interactive apparatus; and
a center-site linkage support terminal unit outputting information representing operation contents regarding the auxiliaries excluded from automatic control based on an operation signal outputted from the general automation computer;
whereinthe electric power plant general control system is configured to be provided with a mock-up portion equivalent to the sequencer function portion of the side of the unit computer, on the side of the general automation computer, so as to output information representing the operation contents regarding the auxiliaries on the center-site linkage support terminal unit through the mock-up portion, and is configured so as to control generally the auxiliaries of the first and the second power generating units by the operation signal outputted from the general automation computer. - View Dependent Claims (6, 7, 8)
