Simulation of the Static VAR Compensator Culiacan Three Substation for the Analysis of Transients

Since its emergence in the late 60’s the FACTS (Flexible AC Transmission Systems) have been and continue to be studied and implemented in all electrical networks around the world, becoming an essential element for stability, control and maximum exploitation of thereof. One of the most used FACTS devices is the Static VAR Compensator or SVC. In this work, the modeling in Simulink of the Static VAR Compensator installed at the substation Culiacán Tres (CUT) belonging to CFE is presented. The SVC is the ability of ±100 MVAR and ABB brand. The modeling was performed to visually program in detail the different subsystems in Simulink such as the timing unit, the TSC (thyristor switched capacitor), TCR (thyristor controlled reactors), filters of the 5th and the 7th harmonic, the transformer bank, the control unit, distribution unit and the measurement unit. Data for major components were taken from data sheet and equipment manuals. ASPEN software was used in order to obtain Thevenin equivalent of the EPS to connect to them the SVC model to test the step and three-phase short circuit. The results of these tests were compared with test results of commissioning of the SVC.
