The paper presents the conceptions of Minimum Generating Subnetwork and Simplified Network for Partial Link correspoding to the tasks correlated with concrete problem in multilayer network schedule, and discusses the generating steps and the time parameters of simplified network for partial link.

New algorithm for computing ventilation network reliability based on network simplification technology;

Compared with similar achievements both at home and abroad, automatic identification of diagonal branches, network simplification and automatic plotting of ventilation network characteristic graph are the particular functions of the simulation system.

Harmonic equivalence network simplification method is proposed to analyze the changing process of transformer substation equivalence network along with different operation modes of capacitors under all the odd harmonics and to find out potential harmonic resonance amplifications from capacitor circuits.

This article puts forword a method for network simplification in power loss calculation of a distribution network,this method is analysed that it can meet the demand of veracity.
