Deepakkumar Yadav Sample Blackout at National Level (Case Studies) Our country’s grid is divided into five electrical regions-Northern, Eastern, Western, North Eastern and Southern. The grid frequency is to be maintained within specified limit (49.7 Hz to 50.05 Hz) by each regional load despatch centre. In 2012, the four grids were synchronized and were collectively called NEW … Read more
Electrical Grid System Different power plants Interconnected in common network form a grid. In broad sense we can say that the grid consists of (1) Generating stations, M.V. transmission lines, (m) Distribution lines and utility i.e. customer’s consuming power. Types of Electrical Grids : Regional grid National grid (1) Regional grid : It is formed by … Read more

Load Dispatching Facilities The centralized control supervises the following : Reliability of service. Quality of service. Economy of production The facilities required for centralized control system are as follows : Dispatching Boards : A load dispatcher must be familiar with every operating function associated with generation, transmission and distribution of electrical energy. He must have … Read more
Load Dispatching As the electric systems expand and are interconnected by grid, a centralized control system or load dispatching become essential. Formerly an individual power house was used to supply its own local load. When generating stations are interconnected, systems operating under different authorities are support supply the total demand of load. Hence, it becomes … Read more

Most Economical Loading of Interconnected Stations Consider power stations S1 and S2. Let PL1 and PL2 be the local loads of stations S1 and S2 respectively. Let PS and PR be the powers sent and received by S1 and S2 respectively as shown in figure A. Let, PL1 = Power input of station S1 = … Read more
Necessity of Reactance for Interconnected Stations Figure A Consider two stations A and B which are being operated in parallel as shown in Figure A. A reactor or an inductance is connected between the busbars of the two systems. Let the load over station B be more than what it can supply (generate), so the … Read more
Economic Loading of Interconnected Stations When number of generators are running in parallel in a generating station each of them can be loaded in such a way that it works at its maximum efficiency condition. Power systems are operated economically because it reduces the cost of fuel required for operation of the power system. Economic … Read more
