A lighting system and method for a main control room of a nuclear power plant

Abstract

The invention provides a lighting system and method for the main control room of a nuclear power plant. The system includes: an emergency lighting module of column A, an emergency lighting module of column B, a safety lighting module of the main control room, and an off-site power supply; the emergency lighting module of column A includes: One UPS power supply, emergency diesel generator in column A, emergency lighting box in column A, emergency lighting lamp in column A; the emergency lighting module in column B includes: the first UPS power supply in column B, emergency diesel generator in column B, emergency lighting box in column B, B column emergency lighting; safety lighting module includes: A column second UPS power supply, B column second UPS power supply, dual power switching device, main control room safety lighting box, relay, main control room safety lighting, main control room safety The lighting lamps, the emergency lighting lamps of row A and the emergency lighting lamps of row B are all the same type of light source; the invention solves the problem of poor visual effect caused by the simultaneous operation of safety lighting and emergency lighting and the lighting of the main control room during the starting process of the emergency diesel generator. The problem of unsuitable lighting caused by switching.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a lighting system and method for a main control room of a nuclear power plant. Background technique [0002] The main control room of the nuclear power plant is the place where the operation control of the operation and accident state of the nuclear power plant is carried out, and it is also the workplace of the operation control group in the emergency organization of the operating unit of the nuclear power plant during the emergency response period. In addition, the main control room concentrates the control and monitoring of the main systems of the entire unit. Under normal operating conditions and accident conditions, it is necessary to ensure that the main control room has sufficient lighting so that the operations in the main control room can be performed normally. The lighting system of the main control room of a nuclear power plant is a system related to quality. ...
