Abstract


Distribution network is an important part of the power system . Distribution network fails, the complex structure of the distribution network , and its precise location of the point of failure has been a difficult and hot research . Thesis rural 10kV distribution network fault location for discussion and research. This paper summarizes the various existing fault location methods, the use TWACS detect distribution network failures, fault section presents fault component -based positioning method and the impedance of the Combination of two-terminal fault location method to determine the point of failure . Two way communication technology is the use of its failure before and after the mutation modulated signal by demodulating information to identify the line fault. Fault section targeting rule by calculating the transient current of each segment , according to the absolute maximum transient current fault section , determine the fault zone . Finally based on the double-end fault component positioning method, by obtaining fault line ends after the amount of sampled data mutation , the use of fault component theory, application of symmetrical components method to calculate the fault component across the positive sequence component , according to the established distribution network model the distribution line voltage to determine the fault location . Application of Matlab / Simulink simulation tools to build a distribution network based TWACS simulation model and 10kV distribution network fault simulation model and a simulation study . Simulation results show that the use TWACS technology to identify faults method is effective , using fault location method is feasible , this method is not transition resistance , fault type and line parameters and other factors , which can effectively identify the point of failure position .
