Method and system for adjusting valves of half-speed turbine of nuclear power plant

Abstract

The invention discloses a method for adjusting valves of a half-speed turbine of a nuclear power plant. The method comprises the steps that a high-speed recorder collects operation parameters of the half-speed turbine of the nuclear power plant under the operation state; the characteristic of a sensor of the half-speed turbine of the nuclear power plant is determined according to the operation parameters; the valves of the half-speed turbine of the nuclear power plant are adjusted by a special valve adjusting device according to the characteristic of the sensor, and the adjusting process at least comprises adjusting on a main air valve and / or adjusting on an adjusting valve. As the operation parameters of the half-speed turbine of the nuclear power plant under the operation state are collected by the high-speed recorder, and the valves of the half-speed turbine of the nuclear power plant are adjusted by the special valve adjusting device, an adjusting scheme of the nuclear power plant is optimized. The invention further discloses a system for adjusting the valves of the half-speed turbine of the nuclear power plant.

Description

technical field [0001] The invention belongs to the field of nuclear power design, and more specifically, the invention relates to a valve debugging method and system of a half-speed steam turbine in a nuclear power plant. Background technique [0002] The steam turbine generator set is an important part of the nuclear power plant, and the steam turbine valve is the key equipment for the control and protection of the steam turbine set, and its performance level is very important for the safe and reliable operation of the nuclear power set. Before the actual commissioning and start-up of the half-speed steam turbine in the nuclear power plant, the dynamic / transient working conditions cannot be established because the steam turbine control system has not been connected with the physical equipment, it is difficult to expose and correct many problems related to upstream design and human error, and it is impossible to evaluate the steam turbine control System design and dynamic c...

AI Technical Summary

Problems solved by technology

Therefore, the valve debugging of conventional thermal power is not comprehensive, and the accuracy of the debugging results cannot be quantified, and it is not suitable for half-speed nuclear power units.
