Distribution line microprocessor relay protection system
To enhance power supply reliability for the user terminals in the case of the distribution system to avoid interference by the fault again, rapidly complete the automatic identification, positioning, automatic fault isolation, network reconfiguration until the resumption of supply of non-fault section, a microprocessor-based relay protection device has developed. By use of DSP, device operating realize the real-time measurement, calculation and display for parameters, a combination of difference method with Fourier transform algorithm realize the relay protect for distribution power lines. Sensitive and reliable reflection of the various lines of work and under normal circumstances in non-rapid start to issue warning signal or protection actions in export tripping circuit so that line to security, economic to run.
