Abstract

The invention is applied in the field of nuclear power control, and provides a method for controlling the starting and stopping of a turbo generator set of a nuclear power plant, a device for controlling the starting and stopping of the turbo generator set of the nuclear power plant, and a digital control system (DCS). The method comprises the following steps of: detecting the running state and running parameters of the turbo generator set, the running state and running parameters of an auxiliary system of the turbo generator set, and fault information in the running of the turbo generator set; displaying the detected information on the same function tracking interface in a centralized way; and directly controlling the starting and stopping of the turbo generator set according to the information displayed on the function tracking interface. The method provided by the embodiment of the invention can make an operator directly and rapidly discover the anomaly of the turbo generator set, rapidly and accurately obtain key parameters and judge reasons, so that the operator can directly, rapidly and accurately control and intervene the starting and stopping of the turbo generator set of the nuclear power plant to ensure the security of the turbo generator set of the nuclear power plant.

Description

technical field [0001] The invention belongs to the field of nuclear power control, and in particular relates to a start-stop control method, device and DCS control system of a steam turbine generator set in a nuclear power plant. Background technique [0002] The pressurized water reactor nuclear power plant is mainly composed of three parts: the pressurized water reactor, the primary loop system and the secondary loop system. Nuclear fission occurs in a reactor core made of nuclear fuel inside a pressure vessel. Pressurized water reactors use low-enriched uranium as fuel and light water as the coolant and moderator. The heat released by nuclear fission is taken out of the reactor by the high-pressure water flowing through the primary circuit system in the reactor, and the heat is transferred to the water in the secondary circuit in the steamer generator. The steam produced by the heated water drives a steam turbine, which drives a generator to generate electricity. [0...
