Abstract

The invention relates to a power generator, transmission line and generator-grid early warning and early control method and a system thereof, a method of accurately calculating and controlling the dynamic reserve power of the power generator or the transmission line and a generator-grid coordination early warning and early control system, which can guide a duty worker in a power plant or a substation to tend to a strong power grid direction to coordinate stable operation of the power generator or the transmission line, and hidden instable operation states are alarmed. The dynamic reserve power of the power generator or the transmission line is calculated in real time, a generator-grid coordination PQ curve range is calculated, the power plant or the substation is guided to be adjusted safely and stably, all automatic stable adjustment devices in a substation are ensured to have enough accident reserve adjustment space and effective hot standby, accurate adjustment can be carried out in a system disturbance state, failure due to lacking of the adjustment space is avoided or protection maloperation or secondary disturbance caused by over adjustment can be avoided; and the real-time high quality and the maximization of the whole accident reserve power of the substation can be ensured, and co-management of a generator-grid coordination safe and stable operation mechanism by the substation and the dispatching can be realized.

Description

technical field [0001] The invention relates to the safe and stable operation pre-warning and pre-control of electric systems in power plants and substations. Specifically, it involves an accurate calculation and control method of reserve power of generators and transmission lines, and an early warning and pre-control system for coordinated safe and stable operation of machines and networks. Background technique [0002] In the operation of the power system, operators need to constantly monitor and analyze the operating conditions of the power plant and the power system, and manually or automatically adjust the system and the active and reactive power distribution of the power plant to maintain the system frequency and voltage within the allowable range and ensure the maximum guarantee The system and synchronous generator run stably, and in the abnormal state of the system, it can visually monitor and analyze the disturbance state of the system or generator, analyze the dist...
