Modified Setting Numerical Distance Protection Of Power Transmission Line In Presence of TCSC Using IEC 62850 Communication Protocol
Journal Title: Acta Technica Napocensis- Electronica-Telecomunicatii (Electronics and Telecommunications) - Year 2012, Vol 53, Issue 3
Abstract
This paper presents a study of the performance of numerical distance relay for a 400 kV electrical transmission line compensated by series Flexible AC Transmission System (FACTS) i.e. Thyristor Controlled Series Capacitor (TCSC) is connected in the middle of the transmission line and can be used in voltage mode control or reactive power injection mode, and damping of power system oscillations in high power transfer levels. IEC 61850 is a new international standard for communication networks and systems in substations that defines different message types based on their transfer time requirements. In IEC 61850 based Substation Automation systems (SAS). The effect of the TCSC on the measured impedance at the relaying point is investigated. The setting zones protection deals with the absence and presence of TCSC using IEC 61850 communication protocol for two stations i.e. Principal station and TCSC station with proposed scheme for tele-protection for studies the effects of TCSC insertion on the total impedance of a transmission line protected by MHO distance relay and the modified setting zone rotection in capacitive and inductive mode for three forward zones (Z1, Z2 and Z3) have been investigated in order to prevent circuit breaker nuisance tripping to improve the performances of distance relay protection.
