Abstract

The invention discloses a debugging method and system for a steam turbine regulating system of a nuclear power station. The debugging method comprises the steps of a primary test of a steam turbine control system, a function simulation test of the steam turbine control system, a regulating valve test of a steam turbine and a joint debugging test of a steam turbine regulating system. The debugging method and system for the turbine regulating system of the nuclear power station have the following beneficial effects that the whole set of strict debugging method and system for the turbine regulating system of the nuclear power station is provided, so the steam turbine regulating system can be verified whether to meet the safe and stable operation demands of the nuclear power station in the aspects of function and performance; the test project of the regulating valve test of the steam turbine is newly added; in addition, the following test contents are also newly added, 1, the cooperative capacity between the steam turbine and a reactor is verified on platforms of different power, and the bearing capacity of the reactor is fully considered; 2, the reliability and the high-precision operation of the control system are ensured due to the performance test of the steam turbine control system; 3, the function test and reactor / machine joint debugging test on the steam turbine control system based on a simulator and the large transient test of the steam turbine control system are also added.

Description

technical field [0001] The invention relates to a steam turbine debugging technology, in particular to a debugging method and system for a steam turbine regulating system of a nuclear power plant. Background technique [0002] The steam turbine regulating system is a reliable, high-speed, high-precision control system, which is used to continuously control the speed of the steam turbine and adjust the output power of the steam turbine. At present, domestic thermal power units mainly adopt Industrial IT Symphony series (such as 800xA) of ABB Company, OVATION series of Emerson Company, I / A Sieries of FOXBORO Company, 5000M series of HIACS Company, Xinhua DEH-V steam turbine regulating system, Tele -Perm series (such as SPPA-T3000) and other distributed control systems (DCS), each DCS manufacturer has developed a special steam turbine digital electro-hydraulic control system (DEH) on the basis of their own DCS, which is used to realize the control of the steam turbine regulatin...
