联络变压器附加电势相位角在电压—无功功率控制中的作用

本文着重分析电力系统中联络变压器附加电势相位角这一尚未引起人们注意的控制变量在电压—无功功率优化中的控制作用；论证了在运行和发展规则中，系统中联络变压器附加电势相位角应怎样调节和配合，以及由此带来的系统运行指标的改善；为此，还提出了新的计算机辅助分析方法。对某一实际电力系统的研究表明，这种新的变压器附加电势控制方式将在保持系统所有边界条件的前提下，节约更多的运行费用。

Voltage/Reactive Power Control with Boot Voltage Phase-Angle of Coupling Transformers in Power Systems

The function of boost voltage phase angle of coupling transformer, a potential control variable in power system, is analyzed.The subjects how to regulate and coordinate the phase angles of coupling transfromers, and therefrom, how to improve the indices of power system operation are discussed and a new computer-aided analytical method is developed. Application of this method to a real power system demonstrates that the new control strategy can save much more operational cost and reduce power loss without violating the original operational constraints of this power system.
