Problems solved by technology

[0004] Since the standby feedwater pump is controlled by two power distribution devices, in order to control the same standby feedwater pump through different power distribution devices, it is often necessary to set up two control devices to control the two power distribution devices respectively. , so as to realize whether to provide power for the standby feedwater pump through the first power distribution device or the second power distribution device, but this will cause the problem of decentralized control logic

Abstract

The invention discloses a control device, and belongs to the technical field of automatic control. The device comprises a device selection module, a first state determination module, a second state determination module, a start / stop fault detection module, a fault gathering module and a device start / stop module. The first state determination module is connected with an operation and stop state detection interface of a first distribution device, the second state determination module is connected with an operation and stop state detection interface of a second distribution device, both the firstand second state determination modules are connected with the device selection module, and the device selection module is connected with the device start / stop module so that the device start / stop module controls start or stop of the first and second distribution devices. Thus, the control device is provided with the multiple modules, the control device can be used to control the two distributiondevices, and the problem of scattered control logics is overcome.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a control device. Background technique [0002] With my country's continuous emphasis on nuclear energy technology, the pace of nuclear power construction has been accelerated. The high temperature gas-cooled reactor nuclear power plant demonstration project, as a nuclear power plant with the level of fourth-generation nuclear power, has been put into construction in my country and is expected to be put into operation soon. The high-temperature gas-cooled reactor nuclear power plant demonstration project adopts the working mode of two reactors driving a steam turbine to generate electricity. There are three feed water pumps, one for each of the two reactors, and the other is used as the feed water pump for the two reactors. Spare feed pump. As the standby feedwater pump for two feedwater pumps, it is necessary to distribute power to the standby feedwater pump to ensur...
