摘要:

优质电力园区以最低成本满足用户对电能质量的特殊需求，成为解决电压暂降问题的新途径，已在国内外开 展了广泛的试点应用。针对中国优质电力园区规划缺少经济高效的优化配置方法的实际情况，提出了一种基于过程 免疫力的动态电压恢复器优化配置方法。基于工业过程电压暂降免疫力，以满足用户用电需求为目标，以治理设备 购置费用最低为约束，采用遗传算法对园区供电质量分级制定动态电压恢复器的优化配置方案，实现工业园区电压 暂降治理的经济性。对大型精密温控系统的电压暂降治理装置的优化配置方法进行仿真计算，验证了所提方法的有 效性与经济性。

Abstract:

Premium power park meets the special needs of users for power quality at the lowest cost，and has become a new way to solve the voltage sag problem，which has been widely applied at home and abroad． Aiming at the lack of cost － effective optimization configuration method for premium power park in China，a dynamic voltage restorer optimization configuration method based on process immunity is proposed． To achieve the governance goals for economics and reliability，the genetic algorithm is adopted to optimize the power quality level combining with the process immunity，by the constrains of meeting customers' short － duration voltage variation quality demand and taking the minimum cost of the sag mitigation equipment as the objective． Through the simulation analysis of a precise temperature control system，the proposed configuration scheme is more cost － efficient compared with the traditional one．
