Example Embodiment

[0041] The invention relates to a distribution network situation awareness method based on complex event processing technology and decision tree, wherein:

[0042] Situational awareness is to perceive an element or elements in a specific time and space environment, understand its meaning, and predict its future development trend. Situational awareness in the field of power distribution refers to the perception of operators of the current state of the distribution network and its changing trends in a rapidly changing environment. This perception process involves a large number of variables, including distribution network topology, switch remote signaling, remote measurement information (voltage, current, active power, reactive power), equipment information (equipment parameters, temperature, overload, etc.). These variables are changing every second, and a large number of complex and time-varying data has exceeded the ability of operators to process information. Without the suppo...

Abstract

The invention relates to a power distribution network situation sensing method based on the complex event processing technology and a decision tree, and the method comprises the steps: defining nodes, and generating a decision tree model according to a node rule and status values; obtaining the input data of the decision tree model; calculating and obtaining output data through employing the corresponding formulas of all nodes; comparing the output data of all nodes with expected values, and obtaining the state changes of the nodes; determining the node priority of the decision tree model, and obtaining an inference result. The method greatly improves the capability of a power distribution network for processing mass information and mastering a key situation under the condition of disasters, and provides decision support for the power distribution network for handling natural disasters.
