摘要
标积制动量已在差动保护中得到了应用。本文通过对标积制动量与传统比率制动量进行对比分析，探讨以下几个问题：（１）标积制动判据与比率制动判据的统一性；（２） 扩展标积制动概念以便在差动保护中获得非线性制动特性；（３）在多侧差动保护中应用标积制动的方法。本文还探讨了差动保护的分析方法。
By comparing the product restraint quantity with the ratio restraint quantity which used in the criterion of the differential protection, some new conceptions and schemes are proposed in this paper: (1)Identity of the product restraint criterion and the ratio restraint criterion.(2)Extending the conception of product restraint for getting differential protection with characteristic of non linear restraint. (3)Method of applying the product restraint quantity in the multi side differential protection. At the same time, some other conception of differential protection is described.
