Abstract

The invention discloses a debugging method of a nuclear power station steam turbine control system. The method comprises the steps that a nuclear power station steam turbine control system simulation model is established, the simulation model at least comprises a simulation debugging device; the nuclear power station steam turbine control system is connected with the simulation model, the nuclear power station steam turbine control system at least comprises one of a steam turbine adjusting subsystem, a steam turbine protecting subsystem, a steam turbine monitoring subsystem (GME) and a steam turbine shaft seal subsystem, each subsystem is subjected to simulation debugging through the simulation debugging device, and according to the simulation debugging results, the functions of the subsystems are verified. According to the debugging method of the nuclear power station steam turbine control system, the simulation model is used for being connected with the steam turbine control system, system function verifying is carried out in advance, nuclear power plant debugging scheme optimizing is achieved, the debugging period is shortened, and the risk of steam turbine unexpected halt and the risk of reactor unexpected tripping after a nuclear power unit is started are lowered. In addition, the invention further discloses a debugging device and system of the nuclear power station steam turbine control system.

Description

technical field [0001] The invention belongs to the field of nuclear power design, and more specifically, the invention relates to a debugging method, device and system for a steam turbine control system of a nuclear power plant. Background technique [0002] Nuclear power half-speed steam turbine is the key to the operation control of nuclear power plant units. Before the actual commissioning and start-up of the nuclear power plant half-speed steam turbine, the dynamic / transient working conditions cannot be established because the steam turbine control system has not been connected to the physical equipment, and it is difficult to expose and correct the upstream design. , Many problems related to human error make it impossible to evaluate the design and dynamic characteristics of the turbine control system. Therefore, the commissioning of the steam turbine unit is very necessary. [0003] The commissioning of the steam turbine unit is closely related to the operating condi...
