摘要(Abstract)：

目前大多数交直流混联系统无功优化计算方法还无法考虑直流输电功率调节次数限制,影响了无功优化计算的实际应用。将计及直流功率日调节次数限制的交直流系统无功优化问题的求解分解为96个时间断面的连续无功优化计算、直流输电功率曲线的阶梯化和在确定各个时段直流输电功率情况下的连续无功优化计算3个阶段,较好地解决了交直流混联系统无功优化计算工程化问题。最后用南方电网500 k V主网架系统数据进行了测试,验证了该算法的合理性。并分析了不同直流功率日最大调节次数取值对无功优化计算的影响。

关键词(KeyWords)： 交直流混联系统;无功优化;直流功率日调节次数限制;三阶段算法;阶梯化近似方法
