摘要
特高压、远距离输电系统中,普通固定并联电抗器因为容升和无功潮流的突变显著地限制了线路的传输功率,而采用特高压可控并联电抗器的调节特性可以很好地提高供电质量,提高系统的输电功率和稳定性。提出了特高压可控电抗器可控调节基本原理及调节范围,结合工程实际,得到了在不同负载特性和全补偿条件下,特高压可控电抗器的控制规律,为特高压可控电抗器的工程设计提供了理论基础。
In the UHV (ultra-high voltage) and long-distance power transmission systems, the reactive power tide can change abruptly, and the common non-controlled reactors restrict the circuitry's transmission power evidently. Using UHV controlled shunt reactors can resolve the line frequency operating overvoltage and reduce power grid loss, and improve the power quality and the system's stability. In this paper, the controller g-adjust fundamental principle and regulating ranges of UHV controlled shunt reactors are studied using the p-type equivalent circuit of long lines. To achieve an adaptive control method and range, a novel compensation method and its regulating range is proposed under different loads and compensation degrees. The provided results are the theoretical foundation of the UHV controlled shunt reactor design.
