| Popis: | 96 The electrical power distribution system according to the line disposition construction discrimination for underground feeders and overhead feeders. Their voltages are 11.4 kV and 22.8 kV, respectively. Each feeder has different type consumption and supply area by line segments loading combination. Base on the line parameter models of the lump model, π model and the distribution model. This thesis analyzes the varying of feeder bus voltage and the phase angle by PSS/E load flow software. With the result of bus voltage and the phase angle to investigate the power sensitivity and maximum power delivery of each feeder. Therefore, it is to derive the power margin of each feeder and main transformer to ensure the power boundary. In view of the key-customers by using installed the low-voltage event recorder to measure and record the outage and abnormal power quality event, it is covered the voltage rising suddenly, the voltage reducing suddenly, the voltage interrupt, the frequency changing and the transition of voltage five kind of outage electric power quality event. According the outage data to real-time analyze and judge the power quality. |
