Problems solved by technology

[0005] Since the real-time display and historical records of PAMS parameters on the backup monitoring means of nuclear power plants adopt conventional instrumentation equipment, and are scattered in various parts of the control panel, PAMS parameters cannot be displayed intensively and effectively
When different abnormal working conditions occur in the operation of nuclear power plants, monitoring information and data cannot be obtained in time according to conventional monitoring methods, operators cannot analyze and deal with accidents in time, and cannot fully meet the equipment quality level requirements displayed by the safety level

Abstract

The invention discloses a monitoring mode switching method for a nuclear power plant master control room. The monitoring mode switching method comprises the following steps: judging whether the monitoring mode of a plant computer information and control system (KIC) is available, if not, switching from the monitoring mode of the KIC to the monitoring mode of an auxiliary control panel (ACP); judging whether a common mode fault exists in a plant reactor protection system, if yes, switching from the monitoring mode of the auxiliary control panel to the monitoring mode of a diversity actuation system (DAS). The monitoring mode switching method for the nuclear power plant master control room can efficiently meet the requirement for monitoring under different working conditions during operation of the nuclear power plant; in addition, the invention further discloses a monitoring mode switching system for the nuclear power plant master control room.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and more specifically, the invention relates to a monitoring mode switching method and system for a main control room of a nuclear power plant. Background technique [0002] In the initial stage of a nuclear power plant accident, it is difficult for the operator to immediately judge the cause of the accident that has occurred or is occurring, so it is difficult to make a correct response. For this reason, the protection actions of the safety system of nuclear power plants (such as emergency shutdown of the reactor, emergency core cooling, etc.) are designed to be automatically executed in the initial stage of the accident. However, for design basis accidents and accidents that cannot be predicted (such as the progress of power plant conditions and nuclear safety analysis predictions), the operator must have sufficient information to monitor the development of the accident, so as to take pre...
