变流器滤波回路的技改优化

Technical Improvement and Optimization of Converter Filter Circuit

某风电场东汽风力发电机组科孚德变流器采用的滤波回路熔丝及下端线缆烧坏的情况相当普遍,每年大约有5~8台,且发生的频率较高,对于备件的损耗需求相当大。鉴于此,对该回路进行了技改,以提高风机利用率。

A wind farm east steam wind turbine unit using the Corfu converter in operation filter loop.Fuse and lower end of the cable burnt out situation is quite common,about 5 to 8 sets every year.The frequency of occurrence is relatively high and there is a considerable demand for spare parts.In view of this,the circuit was modified to improve the availability of the fan.
