【正文】 ion of the relay protection principles and setting calculation. Seventh chapter is part of unmanned substation automation systems,focuses on the implementation of the unmanned substation . Through to the 110KV transformer substation design, causes me has to the electrical engineer and its the automated specialized branch curriculum to be prehensive, system grasping, strengthened apply theory to reality the ability, raised the project consciousness, exercised me independently to analyze and the solution electric power project design question ability. Key words: Single busbar main wiring Shortcircuits the putation Transformer protection Unmanned substation automation systems 目錄 摘要 ..................................................................................................................................
