Optimization of Automatic Power Monitoring and Control Method in HVDC Projects

The construction of UHVDC (ultra high voltage direct current) transmission integrates the regional power grids into a whole grid in China, which increase the importance of power grid stability. Automatic power control helps operation personnel reduce the burden of work, but it may also take the power control error risk. The paper briefly investigates an improved method to reduce manual input and the burden of monitoring work for automatic power control. The improved method is based on the Yunnan-Guangdong II 800Kv UHVDC transmission project station SCADA (supervisory control and data acquisition) system. It does well in the project performance and reduce the operator's work burden effectively.
