摘要：

双馈抽水蓄能机组可以通过变速运行灵活调节功率,在发电和抽水工况下均具备一定的调频潜能.为挖掘双馈抽水蓄能机组在不同工况下的调频能力,分别建立其适应不同工况运行特点的调频控制模块,提出计及转速及功率限制的自适应变参数调频策略.首先,在建立考虑可逆式水泵水轮机动态特性的机组模型基础上,构建发电工况下将频率偏差转换为附加功率指令、抽水工况下将频率偏差转换为附加转速指令的调频模块.其次,分析各调频参数对于频率动态响应的影响,并以系统频率偏差最小为目标,以机组的转速及功率限制为约束,提出基于改进粒子群算法的多工况最优调频参数确定方法,在此基础上形成随机组状态实时调整的自适应变参数调频策略.最后,以含双馈抽水蓄能机组的四机两区系统为例进行仿真分析,仿真结果表明:所提调频策略使机组在不同工况、不同运行状态下均具有良好的调频性能.

Abstract:

Doubly-fed pumped storage unit can adjust its power flexibly through variable-speed operation, enabling it to participate in the frequency regulation of the grid in both generating and pumping modes. To explore the frequency regulation capability of doubly-fed pumped storage unit, frequency regulation modules adapted to the characteristics of units under different operating conditions are built, and a frequency regulation strategy with adaptive variable parameters considering the speed and power limit of the unit is proposed. First, based on the dynamic model of the unit considering reversible pump turbine, the frequency regulation modules are built, in which the frequency deviation is converted to additional power command in generating mode but to additional speed command in pumping mode. Then, the impacts of control parameters on the frequency dynamic response are analyzed, and the calculation method of optimal frequency regulation parameters under multi conditions is proposed based on the improved particle swarm optimization algorithm, which aims at minimizing the frequency deviation and takes the speed and power limit of the unit as constraints. Based on the proposed method, an adaptive frequency regulation strategy is further presented in which frequency regulation parameters adjust with the change of operating conditions of the unit. Finally, a four-machine two-zone system model with doubly-fed pumped storage unit is built, and the simulation results show that the frequency regulation strategy proposed can make the unit achieve a great frequency regulation performance under different operating conditions.

Key words: doubly-fed pumped storage unit (DFPSU), primary frequency regulation, speed and power limit, adaptive control, variable coefficient
