摘要

针对分数阶虚拟同步机（FOVSG）在并网运行中,因受到有功指令及电网频率突变影响而导致有功暂态响应与惯量响应特性难以兼顾的问题,提出一种基于超前滞后校正的FOVSG（LLC-FOVSG）并网功频响应优化策略。该策略在FOVSG的转子运动方程中引入超前滞后校正环节以构成LLC-FOVSG,并通过构建LLC-FOVSG并网功频小信号模型,实现控制参数的科学整定。随后,通过搭建100 kV·A时FOVSG仿真模型与硬件测试平台进行对比试验,结果验证所述LLC-FOVSG相较于FOVSG在提升并网系统功频响应性能方面的优越性。

Abstract

To address the challenging of trade-off between the active power transient response and inertia response characteristics of fractional-order virtual synchronous generators （FOVSGs） during grid-connected operation under abrupt variations of the active power command and grid frequency, a grid-connected power-frequency response optimization strategy based on lead-lag correction （LLC-FOVSG） is proposed. This strategy introduces a lead-lag correction block into the rotor motion equation of the FOVSG to constitute the LLC-FOVSG. By constructing a grid-connected power-frequency small-signal model of the LLC-FOVSG, a systematic tuning method for control parameters is achieved. Subsequently, a 100 kV·A FOVSG simulation model and a hardware testing platform are established for comparative tests. The results demonstrate the superiority of the proposed LLC-FOVSG over the conventional FOVSG in enhancing the power-frequency response performance of the grid-connected system.
