基于DSP的主变压器风冷系统控制研究

Research of Main Transformer Wind Cooling System Control Based on DSP

介绍了以DSP作为核心控制器件的大型变压器风冷控制系统的原理和实现方法。该系统实现对主变风冷系统工作状态和故障情况实现本地和远距离在线实时监控。根据运行中变压器的负荷电流、油温和环境温度等条件,进行各类数据的优化判断,自动投入或退出冷却器的运行,实现了完整的风冷控制系统功能。

This paper introduces the principle and method of wind Cooling system of transformer controlled by DSP.This system can monitor the working condition and fault at real time in short or long distance.It will run or stop the radiator automatically,according to the load current and the oil temperature of the transformer with optimal control.The complete wind cooling control system has been realized.
