智能变电站电压并列装置的改进

Improvement of Voltage Paralleling Device in Smart Substation

指出电压并列装置是实现变电站内电压回路切换的重要装置。阐述了在现有大多数智能变电站建设中,电压并列装置仍然沿用了传统变电站的设计方法,即通过控制把手进行手动切换,这样不仅不具备远方操作的功能,而且在与智能回路的配合使用中出现了一些明显的逻辑缺陷。提出了一种电压并列装置逻辑问题的解决办法,并提出了适合用于智能变电站智能电压并列装置的设计思路。

Voltage paralleling device is an important equipment to implement voltage circuit switching. In the construction of smart substation, voltage paralleling devices are still switched manually by handle, which is a traditional method. This method is not only limited in remote operation, but also leads to obvious logical errors. In this paper, solutions are proposed to solve logic problems in voltage paralleling devices and a suitable designing concept is put forward for voltage paralleling devices in smart substation.
