摘　　要：上下层电网无功电压调控失配给电网的安全经济运行带来了较大风险.文中给出了无功电压调控失配的定义,提出了一种无功电压调控失配风险评估模型.通过对反映失配状态的变电站变高侧电压、变低侧电压、关口无功和站内可用无功资源的容量因素进行量化,构建了失配风险评估指标.所开发的无功电压调控组合分析系统可实现设备台账管理、潮流分析、无功电压调控失配风险分析、去失配策略控制效果分析等功能.实例分析表明,该系统具有较好的工程实用价值.As the reactive power/voltage control mismatch between the upper and the lower power networks may result in danger and uneconomic power network operation, a model to evaluate the mismatch risk is proposed after analyzing the concept of mismatch. In this model, a mismatch risk index is constructed by quantizing the high-side voltage, the low-side voltage, the available reactive power and the reactive power on power network boundaries. Moreover, a combinatorial analysis system of reactive power/voltage control is developed, which has such functions as device account managenment, power flow analysis, mismatch risk evaluation and anti-mismatch strategy test. Case study results show that the proposed system is practical and feasible.
