Optimization design on air-cooled system of converting transformer in +800 kV LingzhouConverter Station

Aiming at the problem of air- cooled control system of converting transformer, concretelyanalyzes the logic of air- cooled system such as the functional realization, the strategy selection and therisk prevention, puts forward the optimization design scheme of converting transformer air- cooledsystem in t 800 kV Lingzhou converter station. The application result shows that the optimized air-cooled system logic considering more operation conditions, ensures the safe and stable operation of thetransformer, it can provide technic reference of air- cooled logic design and the functional realizationfor converter station and substation.
