摘要
开放式微机保护满足了用户对保护灵活性的需求。开放式理念的出现,也使微机保护向综合、复杂功能发展提供了可能性。本文以开关量输入功能的灵活配置为例,阐述了开放式保护的特点;提出了内部数据总线的概念,以及如何用内部数据总线构筑继电保护开放平台;保护所具有的可编程方案逻辑(PSL)功能,进一步体现了开放式微机保护的“灵活性”和“易用性”。
The user's demands on protection-flexibility are satisfied by open-type micro computer protection. Due to appearance of open-type concept, the development possibility toward integration & complex function of microcomputer protection has been provided. Taking the flexible collocation of the switching variable input function to be as an example in this paper, the author explained the features of open-type protection, presented internal data bus concept and how to use it to construct relay protection open-platform. As the protection has been with programmable scheme logic (PSL) functions, so that the flexibility & serviceability of open-type microcomputer protection is incarnated further.
