Problems solved by technology
[0003] Usually, the operator controls the reactor circuit through the main control server. When the main control server fails, it will switch to the backup control system. However, it is difficult to determine whether the backup system is available after a phased shutdown. Requirements, direct switching cannot guarantee the safety of the unit
[0004] Since the above-mentioned existing technology only switches the control system when the main control server fails, it leads to the problem that the safety of the unit cannot be guaranteed

An embodiment of the invention discloses a method and a device for checking availability of a nuclear power plant backup control system. The backup control system and a main control server are respectively connected with a reactor loop. The method includes: when a control system of the reactor loop is the main control server, detecting the state of the backup control system in real time; judging whether the backup control system can be started or not according to the state; if yes, when a switching instruction is received finally, switching the control system of the reactor loop from the main control server into the backup control system. When the main control server controls the reactor loop, the stage of the backup control system is considered, so that unit safety is guaranteed when the control system is switched.
Description
technical field [0001] The invention relates to the field of nuclear power. Background technique [0002] In the nuclear power plant system, there are usually two sets of control systems to control the reactor circuit, and the two control systems are the backup control system and the main control server. The backup control system consists of two parts: operating console and monitoring panel. The monitoring panel is equipped with alarm equipment and displays, such as alarm windows, displays and signal units (possibly with some underlying controllers). The console is equipped with controllers, toggle switches and signaling units. The main control server is mainly composed of multiple displays and multiple servers. The operator can control the reactor circuit through the main control server or the backup control system. [0003] Usually, the operator controls the reactor circuit through the main control server. When the main control server fails, it will switch to the backu...
