The embodiment of the present invention discloses an electric-thermal coupling system fault early warning method and early warning device. The method includes acquiring data of electric-thermal coupling system components, determining the initial operating state of the system; sequentially simulating component failures in the electric-thermal coupling system, and updating the system Based on the data, the optimal model is used to determine the load shedding amount caused by the current fault to the system; it is judged whether the load shedding amount exceeds the threshold of the system load shedding amount, and an early warning signal is issued when the threshold is exceeded. The device is respectively connected to the electric-thermal coupling system and the dispatching mechanism. Based on the current operating state of the system, the present invention simulates the impact of expected faults on the electric-thermal coupling system, and provides an early warning signal to the dispatching mechanism to accurately and effectively predict the impact of faults. The regulatory agency can propose a response plan for this failure, so as to avoid serious losses after the actual manuscript failure occurs.
Description
technical field [0001] The invention relates to the technical field of fault prevention and disposal of various energy systems, in particular to a fault early warning method and early warning device for an electric-thermal coupling system. Background technique [0002] With the large-scale application of heat pump technology, the coupling between the power system and the thermal system is becoming more and more close. like figure 1 As shown, the electric-thermal coupling system mainly includes three parts: power system, thermal system and heat pump. The heat pump connects the thermal system and the power system, and consumes the electric energy in the power system to provide thermal energy to the thermal system. The thermal system includes a plurality of thermal nodes, and each thermal node is installed with thermal equipment and thermal loads. The thermal nodes are connected by pipes, and there is water in the pipes as a medium to provide thermal energy to the thermal load...
