Analysis of switching transient and fault detection of strong power system using PLL
Fault protection, phase-locked loop (PLL), power system, transients, fault current limiter.
In power system to discriminate faults from switching transients a new method is proposed in this paper. In this method before the occurrence of first peak of the fault current, fast fault detection and fast fault clearing are essentially required for stable power system. An Example of this system is in an industrial system where bulk power is desired but there high short-circuit currents cannot be measured. Here we are proposing the method of Phase-Locked Loop (PLL) to perform the task of discrimination of Faults and transients. The power system model is developed and simulated for fault performance analysis. MATALB simulations have been performed and the output of the PLL is found completely different for a fault, as compared to a Switching Transient. This difference is being used in this work for discrimination between a fault and a Switching Transient. This capability of discrimination is useful for the safety and stability of the power system.
