变压器比率差动保护调试计算器开发及应用

Development and Application of Debugging Calculator of Transformer Ratio Differential Protection

比率差动保护是变压器的主保护,原理复杂,计算步骤多。在现场调试过程中因参数和原理不同,每次调试需要计算大量数据,导致耗时长,出错率高,给工程技术人员带来较大困难。本文利用Android平台开发了一款适用于比率差动保护调试的计算器,调试类型及方法可选,无须后续升级。经工程实践验证,其计算速度快,结果正确,有效提高了现场调试效率。

Ratio differential protection is the main protection of the transformer, and its principle is complex and calculation steps are more. Because of the different parameters and principles, it need calculating a large number of data in the field debugging process every time. As a result, there are a lot of wasted time and some inevitable mistakes and it brings greater difficulties to the engineering technical personnel. In this paper, the Android platform is used to develop a computer which can be used in the ratio differential protection. The debug type and method of the computer are optional and there is no need to subsequent upgrades. It is proved that the calculation speed is fast and the result is correct in practice .
