摘要:
针对大容量同步调相机接入高压直流输电（HVDC）受端系统后，常规PI励磁控制在故障恢复阶段易出现母线电压超调及振荡的问题，提出一种基于灰色预测模型GM(1,1)的同步调相机PI励磁控制策略。该策略通过对受端母线电压序列进行灰色建模与趋势预测，提前获取电压偏差预测值，并将其作为PI控制器的输入，实现对励磁电压的前瞻性调节。基于CIGRE标准测试系统，构建了PSCAD/EMTDC与MATLAB/Simulink联合仿真平台，在多种典型扰动工况下，对比分析了灰色预测PI控制与常规PI控制的动态响应特性。仿真结果表明：所提控制策略能够有效补偿励磁系统的大惯性滞后，显著抑制母线电压超调并缩短系统调节时间；在三相短路故障下，母线电压最低值提高约4.5 kV，直流输送功率最低值提升约31 MW，系统恢复时间明显缩短。该策略兼具计算量低与实时性强等特点，可为HVDC受端系统同步调相机励磁控制优化提供有效技术途径。
Abstract:
Aiming at the problem that the conventional PI excitation control was prone to bus voltage overshoot and oscillation in the fault recovery stage after the large‑capacity synchronous condenser was connected to the high voltage direct current (HVDC) receiving‑end system, a PI excitation control strategy of synchronous condenser based on grey prediction model GM(1,1) was proposed in this study. In this strategy the predicted value of voltage deviation was obtained in advance by grey modeling and trend prediction of the receiving bus voltage sequence, and was used as the input of the PI controller to realize the forward‑looking adjustment of the excitation voltage. Based on the CIGRE standard test system, a PSCAD/EMTDC and MATLAB/Simulink co‑simulation platform was constructed. Under various typical disturbance conditions, the dynamic response characteristics of grey prediction PI control and conventional PI control were compared and analyzed. The simulation results showed that the proposed control strategy could effectively compensate the large inertia lag of the excitation system, significantly suppress the bus voltage overshoot and shorten the system adjustment time. With the three‑phase short‑circuit fault, the minimum value of bus voltage was increased by about 4.5 kV, the minimum value of DC transmission power was increased by about 31 MW, and the system recovery time was significantly shortened. This method had the characteristics of low computational complexity and strong real‑time performance, which could provide an effective technical way for the optimization of excitation control of synchronous condenser in HVDC receiving‑end system.
