考虑SSSC装置的可用输电能力研究

Available Transfer Capability of Power Network Considering the Static Synchronous Series Compensator

可用输电能力是衡量互联网络安全性与稳定性的重要指标,而灵活交流输电系统是提高系统可用输电能力的有效途径。基于一种串联补偿型的FACTS装置-静止同步串联补偿器,建立了ATC计算的最优潮流模型,在模型中引入了SSSC的功率注入模型,采用原对偶内点法对其进行求解,并且根据特征结构分析法确定了SSSC装置的最佳安装位置。利用IEEE-30节点系统进行了仿真分析,结果验证了该方法的有效性。

Available transfer capacity is the key indicator which measure the security and stability of the interconnected power systems.The flexible AC transmission system is an effective means to improve the available transfer capacity.The paper established the optimal power flow model of available transfer capacity based on a series compensated FACTS device-SSSC,introduced the power injection model of SSSC,and take primal-dual interior point method to solve the problem,meanwhile based on characteristic structure analysis method to select the optimal installation location of SSSC device.Carried on the simulation using the IEEE-30 bus system,the results verified the validity of the method.
