| description | Today important is the scientific study of solutions to the problem of participation of nuclear power plants, both existing and newly built, in the regulation of load schedules.However unacceptable a significant reduction of the capacity factor of nuclear power plants. Sufficient flexible of NPP equipment is the basis not only of the stability of large power systems in modes with violation of the frequency but also safety of the nuclear power plants, Проблемы энергетики, 2017, том 19, № 7-8 95 which would ensure cooling of the reactor during an accident.Therefore, the necessary capabilities of rapid discharges and increase in the load in large nuclear power plants, selected for emergency frequency control. High voltage variable frequency drives (VFD) of the main circulation pumps are able to provide the necessary reserve of growth power.Installation VFD of the MCPs are suitable for saving energy consumption in their drive on the partial regimes and to improve the stability of the neutron-physical active zone characteristics in variable modes.Using VFD of the MCPs can reduce increase pressures in the steam generators in the respective modes, restricting flow the coolant with a constant average temperature in the active zone of reactor, and therefore to reduce the energy consumption of the feed pump. |
