Based on GPS technology, a novel method of live line measuring the zero sequence parameters of T-connection transmission lines with mutual inductance is proposed. The mathematical models of the new method are explained in detail. The hardware structure and digital simulation results are given. Finally, an example of live line measuring two 220kV transmission lines with T-connection branches in South...
Based on GPS technology, a new average current method (ACM) of live line measuring the parameters of transmission lines with mutual inductance is proposed. The mathematical model of the new method is explained in detail. Digital simulation results are shown. Finally, an example of live line measuring four 220-kV transmission lines with mutual inductances in South China power grid is given. Comparison...
For wind farms in near sea, in which doubly-fed induction generator (DFIG) runs, located at different site respectively, multi-terminal VSC-HVDC (Voltage Source Converter based HVDC) helps to resolve connection for each other and transmitting electrical power into main grid. The paper models wind farms, VSC-HVDC, designs control system and specially takes their control together into account in order...
