Time: June 2018.

Location: Yumen, Gansu.

Reasons for renovation: The foreign brand converter used on site has a long operating life. The power module, a core component of the converter, has a high failure rate. As the supplier gradually withdraws from the Chinese wind power market, the spare parts procurement cycle is long and the price is high, resulting in long operation and maintenance time and high operation and maintenance costs.

Renovation scheme: In response to these problems, Hopewind, with many years of experience in converter design and production, has developed a module that can seamlessly replace its power module.

Renovation effect: In June 2018, a replacement verification was carried out, realizing seamless replacement. It has been operating stably until now since the replacement.
