Problems solved by technology

[0003] As the number of nuclear power units in my country increases year by year, the peak-to-valley difference in the power grid widens, and the pressure on nuclear power to participate in power grid peak regulation increases. However, CPR1000 lacks practical experience in flexible operation and lacks a complete implementation system. requirements

Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 As shown, in an embodiment of the present invention, a method for screening a nuclear power plant system to be evaluated is provided, and the method includes:

[0035] Step S1. Detect that the current conditions for entering the system capability demonstration are met, and the conditions include changes in system operating parameters, changes in equipment status, and occurrence of an event affected by the flexible operation of nuclear power units in preset external experience feedback;

[0036] The specific process is that the embodiment of the present invention identifies the systems to be evaluated in nuclear power plants that are affected by the flexible operation of nuclear power units from the three dimensions of system operating param...

Abstract

The invention provides a nuclear power plant under evaluation system screening method. The current condition of meeting access system capacity argument is detected, wherein the condition includes a certain event influenced by FPO in the change of work parameters, the change of the equipment state and the preset external experience feedback; and the corresponding type and the corresponding under evaluation system are selected out of a preset under evaluation system list in a screening way according to the currently detected condition meeting access system capacity argument, wherein the type includes the nuclear island, the conventional island, instrument control and the electrical type. With application of the nuclear power plant under evaluation system screening method, the system influenced by the FPO can be selected in a screening way so that forward-looking technology searching of the flexible operation capacity of the CPR1000 system can be facilitated, and the theoretical support can be provided for the unit to participate in power grid peak regulation.

Description

technical field [0001] The invention relates to the technical field of nuclear power plants, in particular to a method and device for screening systems to be evaluated in nuclear power plants. Background technique [0002] As one of the world's important main power sources, nuclear power has the characteristics of "clean", "stable" and "high efficiency". Therefore, it is necessary to introduce nuclear power technology to keep nuclear power units running at base load all the time, which will help alleviate my country's coal-based energy consumption. make an important contribution to the environmental problems caused by the structure. [0003] As the number of nuclear power units in my country increases year by year, the peak-to-valley difference in the power grid widens, and the pressure on nuclear power to participate in power grid peak regulation increases. However, CPR1000 lacks practical experience in flexible operation and a complete implementation system. The existing lo...
