摘要/Abstract

摘要： 近年来，中国特高压输电工程的投运，对自动发电控制系统进行有效控制带来了新的挑战。数字仿真是进行系统分析的有效手段，但是，在全过程仿真程序中，还没有一种合适的特高压联络线控制策略模型。针对华北—华中互联电网的1 000 kV特高压交流联络线功率控制动态仿真问题，结合以联络线功率控制为目标的AGC控制性能评价标准——T标准，根据特高压联络线控制的要求和现场运行经验，借鉴CPS标准控制策略模型，根据特高压联络线的输送功率偏差与区域控制偏差ACE的乘积，以及乘积量在电网送端控制区和受端控制区的不同特点，提出了一种基于T标准的自动发电控制策略模型。在全过程动态仿真程序PSD-FDS中进行了模型开发实现。使用实际电网数据证明该模型的有效性，证实T标准策略的控制效果比CPS标准策略有所提高。

Abstract: In recent years, the operation ultra-high voltage(UHV) AC projects in China has brought about new challenges to the effective control of automatic generation control system. Digital simulation is an effective means for system analysis. But in the full dynamic simulation program, no control strategy model is suitable for UHV tie-line. In order to dynamically simulate the active power control of the 1 000 kV UHV AC tie-line between the north China power grid and the central China power grid, a new T standard-based automatic generation control(AGC) strategy model is proposed based on the T standard - the AGC performance assessment standard, the controlling requirements of the UHVAC tie-line and field operational experience, the CPS control strategy model, the product of the UHV AC tie-line bias and the area control error(ACE), and the characteristics of the product in the receiving-end system and the sending-end system. The new model is achieved in the full dynamic simulation program (PSD-FDS) and is proved to be effective through simulation case study based on field data. The result of the case study confirms that the T standard strategy has better effectiveness than the CPS standard strategy.
