Low-Voltage Comprehensive Management of Rural Distribution Networks based on MSVC and Line Voltage Regulator
Abstract
Rural distribution networks, as important components of the electrical power system, are important basic conditions for economic development in rural areas. However, weak structure, large supply scope, abundant power supply terminals, and long line and low-voltage phenomenon are relatively common in rural distribution networks in China. A new low-voltage comprehensive management method for distribution networks based on magnetically controlled static var compensator (MSVC) and line voltage regulator was proposed in this study to solve low-voltage problems in rural distribution networks. The computing and MATLAB simulation model was constructed based on the 10kV rural distribution network in Guangdong Province, China. Performances under different problem situations were compared by using voltage and power factor as the reference variables to verify the validity and feasibility of the new method. Results show that, the proposed comprehensive management method based on MSVC and line voltage regulator can improve the voltage and power factor of branch lines without influencing the voltage of other branch lines; thus, the voltage at different nodes satisfies the requirements (>9kV) and increases the power factor to 0.96-0.98. This study proves that the proposed method has unique advantages in increasing voltage, power factor, and economical efficiency of the rural distribution networks. The study also provides effective references to low-voltage management in rural distribution networks.References
