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
Load Allocation Among Various Types of Power Stations When a interconnected system makes use of hydroelectric plant, steam power plants and other types of power stations it is necessary to draw the annual load duration curve of the total system and fit the various types of plants into the area under the curve. The next … Read more
Based Load and Peak Load in Power Plant Every generating station has to respond and supply the varying demand of power throughout the day. Hence, it is necessary that individual generators are required to bring into service or shut down from service depending on whether the load is increasing or decreasing. The peak-load on the station … Read more
Advantages of Power Plant Interconnections Following are the major advantages of interconnecting various power stations and systems : Increased reliability of supply : If one of the power plant fails to supply the load due to fault etc. then the system can be fed from the other stations. Generation of power in a hydro-station is … Read more
Combined Operation of Power Plant Electrical power is being generated in large generating stations, which are either hydro thermal, nuclear power stations. These generating stations are mostly far away from the load centres (i.e, where the load is required). Hence, it is required to erect large and long transmission network to feed the electricity from … Read more
Combined Operation of Hydro Electric and Steam Power Plant Interconnection of these type of generating plants enable the water and fuel resources to be used economically. At the times , when its raining and rivers and lakes are full of flood water, hydro-electric plants can be operated at their maximum capacity so that coal and … Read more
Factors Affecting the Cost of Generation Average Demand The average demand on a station is always referred in particular period i.e. a day, a month or a year. Depending upon this period the average demand is either daily, monthly or yearly. In case of daily average demand = kWH delivered by the station in 24 … Read more
