Abstract

The invention is suitable for the technical field of a reactor control and protection system and provides a nuclear power unit power boost margin monitoring method, device and system. The method comprises steps that a fixed time interval is set, the nuclear power, the thermal power and the loop thermal power in a time segment are collected, and a maximum nuclear power value, a maximum thermal power value and a maximum single-loop thermal power value are obtained; the maximum nuclear power value is compared with a nuclear power peak limit value to obtain a first margin, the maximum thermal power value is compared with a thermal power peak limit value to obtain a second margin, and the maximum single-loop thermal power value is compared with a loop thermal power peak limit value to obtain athird margin; the minimum margin of the first margin, the second margin and the third margin is obtained as a theoretical margin; the boost margin is obtained according to the theoretical margin and apreset fixed margin. The method is advantaged in that the nuclear power unit power boost margin can be monitored and controlled, and full power generation is achieved when the power meets the full power generation condition.

Description

technical field [0001] The invention belongs to the technical field of reactor control and protection systems, and in particular relates to a method, device and system for monitoring the power boost margin of a nuclear power unit. Background technique [0002] At present, the operating power control methods of nuclear power units include: thermal power control and nuclear power control; among them, the thermal power can be close to 99.8% FP, and the nuclear power will be reduced immediately when the maximum value of the nuclear power of the four range channels exceeds 101.5% Pn , and analyze and adjust parameters according to the thermal power situation; based on the current regulations, each unit has not reached full power generation, and the daily operating power of the unit is different. Under certain conditions that can achieve greater power generation, due to The limitation of conditions did not achieve more power generation, but did not realize the full power generatio...
