从电压稳定性和热极限两个方面对配电系统的负荷状况进行了评估。测试中使用的是巴西一家配电公司的真实网络。结果表明，最大负荷可能受电压稳定性的限制，而不受热极限的限制。提出了考虑电压稳定作为配电线路运行负荷的新约束的必要性，包括新用户的接线问题。在配电网扩展研究中应考虑电压稳定约束。新的规划约束可能会避免建造新的线路和变压器，而这些线路和变压器永远不会在已经受到电压稳定压力的系统中得到充分利用。
The loading condition of distribution systems is assessed with respect to voltage stability as well as to thermal limit. Real networks of a distribution utility of Brazil are used in the tests performed. Results show that the maximum loading may be limited by voltage stability rather than by thermal limit. The paper shows the necessity of considering voltage stability as a new constraint on the operational loading of electrical energy distribution feeders, including the connection of new consumers. The voltage stability constraint should be considered in studies concerning distribution systems expansion. The new planning constraint may avoid the building of new lines and transformers which could never be fully used in systems already stressed by voltage stability.
