摘要
发电厂新建机组的设计方案、控制方法、系统结构等比以往发生了深刻的变化,发电机组总启动试验的手段也大有改观,主要在短路试验方法、核相方法、电气控制与DCS的接口、自动准同期系统、试验设备和试验组织方式等方面,对传统的试验方法做了比较大的改进。从而提高了试验操作的准确性,缩短了试验的时间,保证了试验的质量。
The design options, control method and system structure of new units for power plants have changed greatly than ever before. The test means for overall startup of the units are also improved obviously, including the methods for short circuit test, phase check, interface of electrical control with DCS, automatic quasi -synchronizing system, test equipment and organization, etc.. A great improvement has been made for the traditional test method. As a result the accuracy of the test operation has been increased with reduction of test time and guarantee of test quality.
