The study on voltage regulation in Central China Power Grid to suit huge power transmitted Southward through UHV project

摘要

Voltage and reactive power regulation capability of Central China Power Grid is study in the paper when huge power is transmitted Southward through UHV project which will be built in near future. At first, the basic condition of UHV and problem of voltage and reactive power when huge power is transmitted Southward through UHV project are introduced and studied. Then, all voltage regulation methods including Nanyang transformer in plan are analyzed to solve low voltage problem of Nanyang UHV station which caused by huge power transmission. Finally, several advices are brought forward to solve low voltage problem of Nanyang UHV station which caused by huge power transmission.
