| 中文摘要 | 以云广直流2013年"5·26"孤岛调试中单极闭锁试验导致双极闭锁事件为例,分析了孤岛方式下单极闭锁后直流系统无功控制及发电机励磁系统的响应特性。指出了机组电力系统稳定器(PSS)存在的反调现象显著恶化了孤岛系统的过电压问题,直流无功控制对大扰动后频率、电压变化的适应性不足是导致双极闭锁的直接原因。现有直流孤岛过电压控制主要集中在换流站侧,没有充分发挥发电机的电压控制能力。为了更好解决直流闭锁后的过电压问题,还需要深入研究PSS反调的解决方案,并充分发挥机组的励磁调节作用。提出了广域PSS和高压侧电压控制的技术思路并进行了仿真验证。; With the incident of the bipole trip caused by a monopole trip in the on-site commissioning of Yunnan-Guangdong high-voltage direct current(HVDC)islanded operation on May 26,2013as an example,the response characteristics of the HVDC reactive power control and generator excitation system after the monopole trip are analyzed.It is pointed out that the anti-regulation with power system stabilizer(PSS)has significantly worsened the overvoltage problem of the islanding system, and inadequate adaptability of the HVDC reactive power control for the frequency and voltage changes after a large disturbance is the direct cause of the bipole trip.The existing overvoltage controls of the islanded HVDC sending system are mainly concentrated on the converter station side,without fully utilizing the voltage control capabilities of generators.In order to better solve the temporary overvoltage problem after HVDC trips,further study on the solution to the PSS anti-regulation problem is required to bring the role of the excitation regulator into full play.The technological ideas of wide-area PSS and high voltage side voltage control are proposed and verified by simulation. |
