摘要
Abstract
The dynamic unit response ability of thermal power units needs to be improved according to the requirement of grid.An automatic gain control (AGC) load control method based on condensate throttling is presented to improve the load following performance.A coordinated control strategy is designed to harmonize the function of coordinated control system and condensate throttling system.Boiler heat signal is built to set the target of throttling power increment,and throttling power increment model is presented to compensate the load feedback of the unit.The designed control strategy is verified by test on the source-grid combined dispatch control simulation system.Simulation result shows the efficient and safe use of condensate throttling and improvement of unit performance in grid frequency control under the proposed method.关键词
