摘要

Capacitor compensation has been widely used in power system at different voltage levels from last five decades. In addition to this, optimal capacitor configuration has a number of advantages such as reducing losses, improving power factor and so on. Since capacitor supply reactive load locally, they improve the load carrying capability of the lines and therefore plays the same role as redundant lines. Since the capacitor bank is added in discrete steps the objective function is not differentiable and the capacitor placement problem is a mixed integer nonlinear program. This paper proposes a case study of 132kV Raymond substation for loss reduction. A Graph search algorithm is used to optimize the cost function. DIgSAILENT Power Factory software is used to evaluate case study of Raymond Substation.
