变压器有载调压并列运行及分接头控制

On-load Voltage Regulation Parallel Operation and Splice Control of Transformers

现阶段,我国大多数变压器有载调压的控制水平较低,而经济发达地区输配电容量较大,导致对分接头所施加的有载调压频率较高。对变压器并列有载调压来说,只能借助人工命令,采取监视、执行等措施实现半自动有载调压。由于有载调压的发展水平比较低,因此在一定程度上影响了有载调压的应用范围,这对分接头控制技术造成了影响。

At present,the control level of on-load voltage regulation of most transformers in our country is relatively low,while the transmission and distribution capacity in economically developed areas is relatively large,resulting in a higher frequency of on-load voltage regulation applied to taps. For on-load voltage regulation of transformers in parallel,the semiautomatic on-load voltage regulation can only be realized by means of manual command,monitoring and execution. Because the development level of on-load voltage regulation is relatively low,the application scope of on-load voltage regulation is affected to a certain extent,which has an impact on tapping control technology.
