自发电控制在中小型水电厂自动控制系统中的应用

Since the Power Control in Small and Medium Hydropower Plants in the Application of Automatic Control System

水电厂自动发电控制是水电厂安全经济运行的重要内容。水电厂AGC的主要任务是按照预定条件和要求,以迅速、经济的方式自动控制水电厂有功功率来满足系统的需要。根据上游来水量或系统的要求,考虑电厂及机组的运行限制条件,在保证电厂安全运行的前提下,以经济运行为原则,确定电厂机组的运行台数、运行机组的组合和机组间的负荷分配,使机组运行在最优工况下,以最少的耗水发出最多的电能,为电厂创造出最大的经济效益。

Hydropower automatic generation control is an important content of safe and economic operation. Hydropower AGC＇s main tasks are： in accordance with predetermined conditions and requirements in order to quickly and cost - effective manner to meet the active power hydropower plant automation systems. According to the upper stream of water or system requirements, consider the power plant and the unit＇s operation constraints, in ensuring the safe operation of power plants under the premise of the principle of economic operation to determine the number of power units operating units, running a combination of crew and crew between the load distribution, and the unit run in the optimal operating conditions in order to issue a maximum of the minimum water consumption of electricity for the plant to create the greatest economic benefits
