Abstract

The invention belongs to the technical field of nuclear power, and provides a nuclear power system, a turbine and a reactor-turbine coordinative control method and device of the nuclear power system and the turbine. In the nuclear power system, the turbine and the reactor-turbine coordinative control method and device of the nuclear power system and the turbine, running modes of the turbine are detected, and if the running mode of the turbine is switched into the rotation speed mode from the load mode after grid connection, the rotation speed set value, the rotation speed actual measurement value and the rated power of the turbine are obtained; according to the rotation speed set value, the rotation speed actual measurement value and the rated power, the load reference value of the turbineis obtained and fed back to a nuclear island system so that the nuclear island system can adjust the reactor power according to the load reference value, accordingly, a reactor and the turbine are matched in power, and the problem that when an existing turbine is switched into the rotation speed mode from the load mode and runs with loads, power of the reactor and power of the turbine are not matched is solved.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and in particular relates to a nuclear power system, a steam turbine and a reactor coordination control method and device thereof. Background technique [0002] For the secondary circuit nuclear power system, the nuclear power equipment is mainly composed of nuclear island system (primary circuit), conventional island (secondary circuit) system main equipment and auxiliary equipment; among them, the nuclear island system refers to the power control system of the nuclear reactor, and the conventional island system Refers to the steam turbine regulation system. When the nuclear power system is in normal operation, the steam generated by the nuclear island system of the nuclear power plant is used to drive the steam turbine of the conventional island, thereby driving the generator to rotate to generate electricity, so the power coordination control between the nuclear power plant reactor and t...
