Study on the Optimal Location of SMES in Power System

Abstract

With the development of high temperature superconducting wire and related cryogenic technology, applications of superconducting device in power system has become the new hot spot of power engineering science research. As a perfect union of two revolutionary technologies, superconducting technology and FACTS, Superconducting Magnetic Energy Storage device (SMES) have superior properties and wide application. This article presents methods to selecting installation site of SMES device in the power system.

Location Method of Underground Pipeline Monitoring Point Based on Cavity Detection

“…Along with the quick city development, urban construction changes daily, the urban underground pipeline construction accelerates constantly, with urban underground pipeline management problems more and more complex, especially having complex effects on the ground and underground construction, and the smooth operation and safety of underground pipeline [1][2][3][4]. Underground cavity problems caused by all reasons can't be ignored, which may cause the ground collapse, leading to the water supply, gas, water drainage, heating, communication and other pipeline damages, and even makes the ground building damaged and extremely easily causes losses of lives and property [5][6][7][8][9][10]. The surrounding environment especially the underground cavity, and the urban underground pipeline operation influences each other, major pipeline accidents occur frequently.…”
