摘要
变压器式可控电抗器(controllable reactor of transformer type,CRT)是用来保证高压输电系统安全运行的重要设备。限流电感是CRT的重要组成部分,合适的限流电感参数是CRT能安全正常工作的基本保障。文中主要提出了一种新的限流电感参数计算方法。首先给出了顺次单支路工作模式下CRT的绕组电流计算模型;然后,基于绕组电流计算公式,建立了限流电感的计算模型;最后,设计算例验证文中所提出精确算法的正确性,并和已有的递推算法进行比较,发现文中所提出的限流电感计算方法在满足谐波要求的基础上更精确合理。
Controllable Reactor of Transformer Type(CRT) is an important equipment used to ensure the safe operation of high-voltage transmission system. Current-limiting inductance is an important part of CRT. The suitable current-limiting inductance parameter is basic guarantee for safe and normal operation of CRT. In this paper,a new calculation method of current-limiting inductance parameter is proposed. Firstly,the winding current calculation model of CRT under sequential single branch operation mode is given. Then,based on the calculation formula of winding current,the calculation model of current-limiting inductance is established. Finally,a concrete example is presented to verify correctness of the accurate algorithm method for current-limiting inductance which is proposed in this paper. By comparing with the existing recursive algorithm,it is found that the calculation method of current-limiting inductance which is proposed in this paper is more accurate and reasonable on the basis of satisfying harmonic demand.
