Abstract

The invention discloses a safe operation control method for a distribution network. According to the method, a fault probability model is constructed by obtaining current operation data of distribution network equipment and a healthy operation process, so that an operation risk of the distribution network can be determined rapidly. When an operational risk occurs in the distribution network, the operation state and a sample in a sample base can be compared rapidly; if a sample identical with or similar to a target state exists in the sample base, a control strategy of the target state is generated by using a sample control strategy as a reference. Compared with the prior art, the method has the advantages of low complexity, high evaluation efficiency, accurate control strategy and fast execution.

Description

Technical field [0001] The invention relates to the field of power transmission and distribution, in particular to a method for managing and controlling the safe operation of a distribution network. Background technique [0002] The smart distribution network is an important part of the power grid. With the increasing requirements of users for power quality in recent years, the improvement of the overall performance of the distribution network has become an important part of the sustainable and healthy development of the power industry. The failure of the distribution network is an important factor affecting the quality of power and the reliability of power supply. Only when the safe and stable operation of the distribution network is ensured can the safe and reliable operation of the entire power grid be guaranteed. Therefore, it is very necessary to carry out more work in the field of distribution network security defense, and to conduct research on the risk assessment met...
