Design and Implementation for Wide Area Power System Monitoring and Protection Using Phasor Measuring Units
Authors: , , ,
Abstract: The increasing demand of load without considerable increase in transmission resources has posed numerous constraints and challenges in the power system monitoring and performance. The inadequacy in transmission resources has resulted in reduced operational margins for many power systems worldwide and has led to operation of power systems closer to their stability limits and to power exchange in new patterns. The issues of deregulation trend in the industry and the requirement of better network monitoring, leads to the development of the solutions for wide area monitoring, protection and control, than the currently used methods which are mostly good for local area monitoring, protection and control. The author set the time-synchronization constraints in monitoring, protection and control of remote node for wide areas to obtain data and take decisions in timely manner, preventing catastrophic consequences. The all got its importance and because of the presence of currently used insufficient methods for monitoring, protection and controlling, which cannot deliver the time-synchronization requirement. The paper gives the PMU model and complete wide area monitoring and controlling system in MATLAB/Simulink and the results are verified through simulations.
