关于主变电量保护定值校验的计算

Calculation of Constant Value Check of Main Transformer Protection

继电保护为一次设备的安全设立了一道屏障,大量事实表明做好继电保护工作对电力系统的安全稳定运行具有重要作用。由于变压器在电网中处于非常重要的地位,一旦它发生故障将给电网的运行带来很大的影响,因此主变保护在继电保护中非常重要。本文针对某主变保护装置,详细分析了主变保护计算步骤。

Relay protection sets up a barrier for the safety of primaryequipment.A large number of facts show that doing a good job of relayprotection plays an important role in the safe and stable operation ofpower system.Because the transformer is in a very important position inthe power grid,once it fails,it will have a great impact on the operationof the power grid,so the main transformer protection is very importantin the relay protection.In this paper,the calculation steps of main transformer protection device are analyzed in detail.
