李家峡水电站计算机监控系统的安装调试

Installation and test of computer supervisory control system for Lijiaxia Hydropower Station

李家峡水电站国产计算机监控系统在工期紧、条件差的情况下，于首台机组发电的同时，顺利、成功地完成了ＬＣＵ与ＰＬＣ自动开停机、自动准同期并网。其计算机监控系统能如期投运主要是软件开发较为成功；此外，其自动化元件的配置与性能较为优良也是一个因素。

The computer supervisory control system for Lijiaxia Hydropower Station has smoothly and successfully completed the automatic start/stop of LCU and PLC and automatic quasi simultaneously connection with the network at the same time when the first generating unit is put into operation,although the construction period is short and the conditions are poor.There are two main factors for the successtul operation of the computer supervisory control system on schedule.One is the successful software development and another is good matching and performances of automatic elements.But during the installation and debugging,some improvements have been made and some elements with poor performances which were found shall be further improved.
