Analysis and Simulation of SCADA system for three-phase recloser circuits in electrical networks.

Abstract:

--------------------------------------------------------ABSTRACT---------------------------------------------------------------A high percentage of transient faults are not cleared correctly, therefore, the electrical service is interrupted, affecting the development of society and the quality index of distribution companies. The objective of this work is to provide a methodology to improve the quality indices in the electrical service, through the simulation of three-phase reclosers in distribution networks through the coordination of SCADA and radio link systems. The foregoing ensures the reduction of TTIK interruption times and FMIK frequencies. The case study uses real data from the three-phase reconnection system located in the middle of the feeder circuit located on Calle Colon of Canton Milagro, province of Guayas–Ecuador, the recloser is linked to the real-time measurement equipment. PMP 450i, which is incorporated into the SCADA system by means of a radio link through an IEC 870 DNP3 communications protocol. The implemented methodology consists of comparing the quality indices of the electrical service interruption reports of CNEL Milagro southern sector, during the period corresponding to the year 2021 and the first semester of 2022, based on the results carried out with the simulation using CYMDIST software throughout the entire feeder network. For this, the subscriber and subscriber module of the PMP 450i measurement equipment was configured and validated by monitoring the failures reported through the SCADA system reports. Through simulation, the study demonstrated that quality indices such as TTIK and FMIK located at one end of the half-span …
