WebElectric distribution grids are seeing an increased penetration of photovoltaic (PV) generation. High PV generation exceeding the grid load demand results in a reverse active power flow in the grid, which raises the voltage level. This paper presents a reactive power controller to overcome the overvoltage problem in the distribution system. A sequentially … WebEquation “Input = output + losses” is valid for any machine. For SG, equation is “Mechanical Input = Electrical output (Active power) + losses”. As written above, if SG is running at high excitation than it may generate reactive power, i.e. SG …

The system should be capable of providing additional amounts of reactive power very quickly (dynamic requirement) since a single failure of a generator or a transmission line (that has to be planned for) has the potential to immediately increase the load on some of the remaining transmission lines. The nature of overhead power lines is that as the load increases, the lines start consuming an increasing amount of reactive power that needs to be replaced. Thus a large trans… WebJan 31, 2002 · In the book Edited by T. J. E.
