在高压输电网络的规划和设计中，有时需要在几个位置安装可控的千乏容量，以在紧急情况下支持母线电压。当输电线路或发电中断导致母线电压幅值降低到期望的极限以下时，就会出现这个问题。选择在哪里以及需要多少千乏容量的问题有许多可行的解决方案，这些解决方案满足所施加的条件。提出了一种以总装机容量最小为目标的求解方法。该非线性规划问题将通过使用线性近似来解决，解决线性规划问题，然后通过使用线性和非线性结果之间的差异来校正线性近似。该方法示出了一个应用程序的一部分，一个大型高压网络。
In the planning and design of a high-voltage transmission network it is sometimes desirable to install controllable kilovar ar capacity at several locations to support bus voltages during emergencies. This problem arises when transmission line or generation outages cause bus voltage magnitudes to decrease below desirable limits. The problem of selecting where and how much kilovar capacity is required has many feasible solutions which satisfy the conditions imposed. A method for locating that solution with the minimum total installed capacity is presented. This nonlinear programming problem will be solved by using a linear approximation, solving the linear programming problem, and then correcting the linear approximation through the use of differences between the linear and nonlinear results. The method is illustrated by an application to a portion of a large high-voltage network.
