What is meant by peaking and frequency regulation

Because the hydro generator startup is relatively simple, so at present widely used hydropower peaking approach; in addition, pumped storage units can be used in the valley pumping to fill in the valley, in the peak power generation peak, that is to say, when the load is in the valley, pumping machine is the use of electricity, it will be converted to electric energy into the potential energy of the water is temporarily stored; once the electricity is in the peak, and then will be This part of the potential energy of water into electrical energy and into the grid. In short, all these measures are greater than the total installed capacity of the peak load as a prerequisite to adjust the operation of generating units as a means.

Power system frequency adjustment

China's power system is our power grid power frequency is 50HZ is what we usually call the frequency of this frequency is the power in a positive spin cycle of the time to decide, f = np/60 where f is the frequency, and n for the generator's rotational speed, for the turbine generator belongs to the high-speed motor for 3000 revolutions per minute, p is the motor of the polar logarithm of the turbine generator, the generator's rotational speed is the frequency of the power system. The number of pole pairs, turbine generator for hidden pole type, thermal power plants for a pair of level and nuclear power plant turbines for 2 pairs of level so that our frequency for 50HZ national regulations in the scope of the 50HZ, plus or minus deviation of not more than 0.2HZ small system can be considered appropriate for plus or minus 0.5HZ and Europe and the United States and Japan, their voltage and frequency of 60HZ is in fact, not much difference, the quality of electricity to be a little bit better. A little.
