Abstract: A monitoring and control system includes a monitoring and control apparatus that transmits an instruction signal for instructing to control a target device to transmission destinations on a first and a second network by a transmission method that designates a plurality of transmission destinations and does not require responses from the transmission destinations, a controller that controls the target device according to the instruction signal and transmits process data indicating a process of the control to transmission destinations on the first and second networks by the transmission method, a transmitter that transmits the instruction signal and the process data to transmission destinations on the second network, a receiver that receives and transfers the instruction signal and the process data addressed to the transmission destinations on the second network and transmitted from the transmitter, and a monitor that receives the instruction signal and the process data.

Abstract: In one embodiment, a remote monitoring system includes a monitoring apparatus displaying a screen for monitoring a power plant, a remote monitoring apparatus displaying the screen transferred from the monitoring apparatus, and a management server managing information regarding the remote monitoring apparatus. The management server includes an activation management module to acquire apparatus identification information for identifying the remote monitoring apparatus, and to return activation permission to the remote monitoring apparatus if the apparatus identification information matches apparatus identification information registered previously.

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.

Abstract: A generation unit general monitor-control system for generally monitoring and controlling electric power generation units (A-3 etc.), the general monitor-control system allocating relations between the electric power generation units and interface devices (11) for monitoring and controlling the generation units.

Abstract: A system for operating a plurality of power generation stations. The system comprises: a general control device for monitoring a plurality of power generation stations, each of the stations including at least one electric power generation unit; a plurality of unit control devices, each of which monitoring each of the generation units, the unit control devices producing alarm data; and communication means for exchanging data between the general control device and each of the unit control devices. Only part of the alarm data produced in the unit control devices are displayed at the general control device.
