The Research on Preventing Mal-Operation Algorithms in Distribution Network

Abstract

To analyze the operating orders in distribution network with multi-power supply and prevent mal-operation, the topological analysis algorithm and the logic-based analysis algorithm are proposed in this paper. In the topological analysis algorithm, the procedures of opening and closing breakers, isolating switches, and grounding device are expounded, which are based on the topological information of distribution network. In the logic-based analysis algorithm, the operating orders are analyzed according the collocated logical expressions. It needs abundant of artificial information, but it has strong ability to express. The experimental results show these algorithms can determine the simulating operation orders in short response time.

Graph-Based Temporary Ground Wire Management in Distribution Network

“…Another difficulty for temporary ground wire management is how to blend the ground wire information into the existed Preventing Electric Mal-operation System (PEMS) [17] . An Auto-generation of Operation Order is proposed in [18], while the Logic-based Analysis Algorithm (LAA) and the Topological Analysis Algorithm (TAA) for preventing mal-operations are proposed in [19]. LAA has good ability to express, but it needs abundant of artificial information.…”
