摘　　要：通过在RTDS中对某实际电网进行无功优化前后的系统网损和电压对比分析来验证在线无功优化算法的效果。首先,在RTDS平台上构建仿真系统模型和运行系统模型,得到无功优化前的系统网损和电压;然后,提出一种无功优化模型,用原始—对偶内点法求解得到优化控制策略并在RTDS平台上实现;再进行了系统无功补偿前与补偿后的网损及电压比对;最后,以某实际电网为例,仿真验证了在线无功优化算法的实现效果。所提为检测在线无功优化算法和自动电压控制系统提供了方法。Comparing system losses and bus voltages of an actual power grid between the results of before and after reactive power optimization, the effect of the online reactive optimization algorithm is verified. Firstly, system simulation model and operation model are built in RTDS, system losses and voltages are gotten. Then a reactive power optimization model is presented and the optimal reactive control strategies are obtained by prime-dual interior point method , realization of the optimal reactive control strategies in RTDS simulation and comparison system losses and voltages between reactive compensation before and after. Taking one local power grid as an example, the effect of online reactive power optimization algorithm, is verified by the simulation results. The proposed method provides a way for checking online application of reactive optimization algorithms and AVC system.
