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...

Problems solved by technology

However, the simulation and debugging device of Alstom half-speed steam turbine has not established a steam turbine model, and cannot perform simulation tests of dynamic functions such as unit rush, load increase, load shedding, and unit shutdown; at the same time, due to the The simulation debugging device uses the system platform to switch to the simulation mode to meet the functional requirements of the simulation simulation, which has inherent defects such as poor tracking, large deviations between some simulation test results and assumptions, out-of-synchronization of stackers, and inability to verify as a whole
