大容量的FACTS装置存在造价高、功耗大、电磁干扰强等问题,实际应用中装置的补偿容量有限。当系统所需的补偿容量大于装置的补偿能力时,如何选择合适的补偿策略达到最优的补偿效果,在装置的实用化过程中有着重要的作用。介绍了差异化级联型电流质量调节装置的设计原理和多个补偿功能,将装置补偿方案的选择和其补偿能力相结合,主要讨论了在装置补偿容量不足的情况下,几种补偿方法的优劣。提出将遗传算法应用到装置的补偿策略中,优化分配装置多个补偿目标的补偿容量,达到多目标协调优化的方法。并通过实际算例,验证了该方法的优越性。
Large-capacity FACTS devices have the problems of high cost, large power consumption and strong electromagnetic interference. The compensation capacity of the devices in practical applications is limited. When the required compensation capacity of the system is greater than the compensation capacity of the device, how to choose the appropriate compensation strategy to achieve the optimal compensation effect plays an important role in the practical application of the device. The design principle and multiple compensation functions of differential cascaded current-quality regulator are introduced. The choice of compensation scheme and the compensation capability of the device are combined. The effects of several compensation methods in the case of insufficient compensation capacity are discussed Pros and cons. The genetic algorithm is proposed to be applied to the compensation strategy of the device, and the compensation capacity of multiple compensation targets in the distribution device is optimized to achieve multi-objective coordination and optimization. Through the actual example, the superiority of this method is verified.
