Novel protection method for VSC‐HVDC transmission lines

A Review on Protection of Transmission Lines

The growth of a country is scaled by the amount of energy it consumes. In the developing India, with the rise of population, increasing number of cities and demanding villages, caused to set up transmission lines with higher capacity. Inter-ties were connected through the transmission lines to lighten every city and village, thus making the whole system complex. This complex system required a r...

A New Approach to Current Differential Protection for Transmission LInes

Online Voltage Stability Monitoring and Prediction by Using Support Vector Machine Considering Overcurrent Protection for Transmission Lines

In this paper, a novel method is proposed to monitor the power system voltage stability using Support Vector Machine (SVM) by implementing real-time data received from the Wide Area Measurement System (WAMS). In this study, the effects of the protection schemes on the voltage magnitude of the buses are considered while they have not been investigated in previous researches. Considering overcurr...

Protection scheme for transmission lines based on correlation coefficients

In modern digital power system protection systems, statistical coefficients technique is recently used for fault analysis. A correlation technique is developed for faults detection and discrimination. The proposed technique is able to accurately identify the condition of phase(s) involved in all ten types of shunt faults that may occur in extra high-voltage transmission lines under different fa...

A Novel Method to Increase the Power Capacity of Transmission Lines Using Transformerless Static Synchronous Series Compensator

In this paper a transformerless Static Synchronous Series Compensator (SSSC) to increase the power capacity of a 230 kV transmission line is proposed. In order to eliminate the transformer, a 15-level cascade H Bridge (CHB) inverter is employed within the proposed compensator structure to inject reactive power to the transmission line. The theory of instantaneous p-q power using in the compensa...
