The embodiment of the invention discloses a power plant production and management control system, and relates to the technical field of thermal power generation. The power plant production and management control system comprises an automatic control unit and a data collecting and calculating unit. The automatic control unit is used for being connected with unit devices in a combined circulating system, and the unit devices are controlled to operate through control instructions without manual intervention so that breakpoint-free automatic operating can be achieved. The data collecting and calculating unit is used for monitoring the current operating parameter of a unit when the combined circulating system operates and calculating and generating an operating strategy according to the current operating parameter of the unit so as to automatically control the combined circulating system through the operating strategy. Breakpoint-free unit-level starting and stopping without manual intervention of the unit can be achieved, and therefore the problem that automatic production and management control is hard to achieve through a power plant production and management control system in the prior art is solved.
