Analysis of Reactive Power Exchanging between Converter Station from YunGuang ±800Kv UHVDC Projection

The paper analysis the yunguang UHVDC system requires exchanging reactive power with AC busbar while transmitting active power. In order to satisfy the operation requirement of converter station under different AC and DC operation modes, the paper centers on switching AC filter and reactive power values under different active power transmission, operate modes and DC voltages. The conclusion has been applied in yunguang UHVDC and is very useful for the UHVDC project.
