论文摘要
相移变压器(PST)用于通过整个设备的相角调节来控制或阻止某些真实功率的流动。它的功能对于特殊情况至关重要,例如消除环路流过一个区域以及平衡平行路径之间的真实功率流。阻抗校正表用于建模,使变压器的阻抗通常随相位角移的函数而变化。如果忽略了这种变化的阻抗的影响,本文的重点是考虑建模错误。使用37个总线测试用例和10,000个总线合成功率网格通过不同的情况测试模拟。结果验证了阻抗校正因子的重要作用,以获得更准确和最佳的功率解决方案。
Phase Shifting Transformers (PST) are used to control or block certain flows of real power through phase angle regulation across the device. Its functionality is crucial to special situations such as eliminating loop flow through an area and balancing real power flow between parallel paths. Impedance correction tables are used to model that the impedance of phase shifting transformers often vary as a function of their phase angle shift. The focus of this paper is to consider the modeling errors if the impact of this changing impedance is ignored. The simulations are tested through different scenarios using a 37-bus test case and a 10,000-bus synthetic power grid. The results verify the important role of impedance correction factor to get more accurate and optimal power solutions.
