Abstract

The invention provides a determining method and device for RB (Runback) project parameters in a power system. The method comprises the following steps of: establishing dynamic characteristics among main parameters of a unit corresponding to an RB project according to a main parameter disturbance test; establishing a system simulation model corresponding to the RB project according to actual work; performing RB project simulation test in the system simulation model according to the dynamic characteristics among main parameters; and determining the RB project parameters according to an RB project simulation test result. Through the invention, the success rate and stability of the actual RB test can be improved.

Description

technical field [0001] The present invention relates to a power system, in particular to a method and device for determining RB project parameters in the power system. Background technique [0002] When a thermal power unit trips due to a failure of an important auxiliary machine, it loses part of its load capacity instantly, and it is a severe challenge for the rapid response and stable operation of the unit control. The design purpose of the rapid load reduction function (RUNBACK, hereinafter referred to as RB) of the unit is to ensure that under the rapid transient working condition when the main auxiliary machine of the unit fails, through logical judgment and control strategies under various working conditions and operating modes The selection can automatically reduce the load of the unit to the target load corresponding to the allowable output of the current operating equipment, and at the same time ensure that the main regulation system works normally and maintain the...
