【摘要】：分析了云南省内已投运水电机组一次调频与自动发电控制(AGC)的典型控制策略,通过工程试验及数据分析,逐一指出其特点及不足。提出功率控制模式下机组采用斜坡函数作为AGC负荷指令,及采用比例—积分—微分(PID)变参数控制分别满足AGC负荷调节和一次调频响应的不同要求;开度控制模式下机组一次调频动作方向与AGC负荷指令方向相反时应屏蔽AGC负荷指令,以及AGC负荷指令首先响应时,应短暂屏蔽一次调频功能等策略。优化了一次调频与AGC间的逻辑关系,并对文中的典型控制策略给出了合理的可行性建议,为水电机组一次调频与AGC寻找更理想的配合策略提供了参考依据。
[Abstract]:Analysis of Yunnan province has been put into operation of hydropower unit primary frequency control and automatic generation control (AGC) of the typical control strategy, through the analysis and engineering test data, pointed out that its characteristics and disadvantages. Put forward power control mode with ramp function as AGC load instruction, and the proportional integral differential (PID) control with variable parameters respectively, to meet the different requirements of primary frequency regulation and response of the AGC load control mode; open unit primary frequency action direction and AGC load instruction in the opposite direction should be shielded AGC load instructions and AGC load instructions first response should be short, shielding an FM function strategy. To optimize the logical relationship of primary frequency modulation with AGC, and the typical control strategy in this paper is feasible and reasonable suggestions, provide a reference for an FM and AGC hydroelectric generating units for better coordination strategy.
