一种基于数据库的中压开关柜一次系统图显示方法的实现

An implementation on the new method of displaying primary system diagram of middle-voltage switchgear based on the database

在电力系统中,中压开关柜一次系统图在各种测量及保护装置中的在线显示和实现非常重要。如何建立字模数据库以及如何实现对字模库的调用是实现系统图在线显示的关键。利用数据库的若干特点,引入了一种新的建立字模库的方法,极大减少了字模库的容量。同时对一次系统的方案进行了仔细的分析,并将其分区,使得方案的组合非常灵活,显示的实现也极为方便。

In the power supplying system,the implementation of the online displaying of the primary system diagrams of middle-voltage switchgear in various measuring and protection device is very important. It is the key point that how to create and call up the font character database. The new method of creating the font character database by using some features of database,which greatly decreases the capacity of font character database. The online displaying of the primary system scheme is analyzed and partitioned, the scheme structure is feasible, and the displaying implementation is convenienet.
