| 摘 要： | 针对电力系统中存在的暂态稳定性问题，为保证足够的传输功率且不必在故障时切机，考虑同时采用晶闸管控串联补偿器(TCSC)和静止无功补偿器(SVC)来提高系统保持同步的能力。采用多机系统中TCSC和SVC以能量函数法为指导的控制策略，不仅能提高系统功角稳定，而且与网络参数无关，具有较强的鲁棒性。对于典型的高压远距离交流输电系统，采用NETOMAC仿真软件进行了仿真，研究了TCSC和SVC以及一些辅助措施在各种严重故障下对提高系统暂态稳定性的作用。通过比较证实了所采用的控制策略具有有效性和优越性。

| Abstract: | In order to avoid shedding generators when power system are subject to severe faults, TCSC and SVC can help greatly to improve system ability in maintaining synchronism. An energy function based control strategy for TCSC and SVC in multi-machine system is adopted. It is demonstrated in the paper that not only the angle stability can be improved by the proposed strategy, but also robustness to the variations of network topology can be obtained in certain cases. The effect of TCSC and SVC to improve transient stability of a typical high-voltage and long-distance AC transmission system is verified under all kinds of severe faults by simulation work carried out by the NETOMAC software. At the same time some supplementary stability-enhancing methods are considered and studied. |
