摘要

the system of automatic control of feed water to the steam generators energy blocks containing a proportional - integral regulators equi u0437u0432u043eu0434u0438u0442u0435u043bu044cu043du043eu0441u0442u0438 nutrient pumps on the number of turbines, to the first and second u0432u0445u043eu0434u0430u043c each of which are connected in common nutritious feed water pressure sensor the manifold pressure sensor, and a steam turbinein the circuit of which is u0430u043fu0435u0440u0438u043eu0434u0438u0447u0435u0441u043au043eu0435 link, characterized by the fact that, in order to improve the accuracy of control for the energy block with separated heat therefore, several schemes of turbines, to the third and fourth gate of each controller additionally connected sensor output of the pump and u043fu0440u043eu0442u0438u0432u043eu0444u0430u0437u043d s and correcting unitto the front of which are connected in u043fu0440u043eu0442u0438u0432u043eu0444u0430u0437u0430u0445 sensors of u0434u0435u0430u044du0440u0430u0442u043eu0440u0430u0445 turbines.
