Black Start Procedure
Black Start Procedure Introduction: Modern power system is operated in grid mode. Various interconnected power systems operating in synchronous. Grid mode operation is stable due to large system bias and high inertia. Also seasonal and daily diversity in load and generation pattern is favorable for optimum utilization of resources and cost of power. However operational coordination is a task. Indian grid is monitor and control by SLDC, RLDC and NLDC at appropriate levels. Grid system operating within limit of angular stability, voltage stability and frequency is secure. Operation near or beyond the limit is highly risky. System downfall starts with generator cascading or network cascading and ends in total collapse having total power failure in large area. Electricity is used for various purposes like heating, cooling, pumping, lifting, moving, cutting, polishing, lighting and so on. But use for lighting is most common by mass. Hence practically word LIGHT become...
