Abstract
In order to achieve the desired flexibility,high efficiency,and cost-effectiveness in the startup and operation of thermal power units,the utilization of the BEST small steam turbine with a small generator for the implementation of a double-turbine reheat system unit is crucial for enhancing the operational economy of the unit.According to the starting mode of the BEST system and unit,combined with the historical process and data of the starting and operation of the debugging and adjustment test,a characteristic analysis test of the BEST system in multi-mode startup and operation was conducted.The existing control logic was optimized,and an operation control strategy for the BEST small steam turbine with a small generator was proposed.The system addresses the issue of lacking control strategies in various aspects,such as the starting and control of the BEST system,converter start-stop control,BEST small steam turbine and converter non-disturbance switching,run back,load dumping conditions,and ensures uninterrupted operation control of the entire process of the BEST system.After optimization,the crucial parameters of the BEST system remain secure and stable during operation.The control method holds significant reference value for similar units equipped with the BEST system.关键词
