在智能电网的推动下，由于新的控制策略和新的发电和配电相关技术的部署，独特和多变的电力系统条件已经开始出现。一项特殊的挑战涉及确保保护计划的正确和可靠运作。以自适应整定选择的形式实施更智能的保护是解决某些保护性能问题的一种方式。然而，引入这种新的方法，特别是对安全关键系统，如保护，有一定的风险因素。此外，将新的二次系统集成到变电站是一个复杂且昂贵的过程。为此，本文提出了一种自适应保护体系结构，该体系结构便于将这些方案集成到作为智能电网的主要组成部分的现代数字化变电站中。该体系结构的功能特性还通过适合重用的自包含模块提供了强大的降低风险方案和灵活实现的手段。给出了一个自适应距离保护方案的实例，并对该方案进行了测试，以演示该结构如何实现，并突出了该结构的新颖特性。
Unique and varied power system conditions are already being experienced as a result of the deployment of novel control strategies and new generation and distribution related technologies driven by the smart grid. A particular challenge is related to ensuring the correct and reliable operation of protection schemes. Implementing smarter protection in the form of adaptive setting selection is one way of tackling some of the protection performance issues. However, introducing such new approaches especially to safety critical systems such as protection carries an element of risk. Furthermore, integrating new secondary systems into the substation is a complex and costly procedure. To this end, this paper proposes an adaptive protection architecture that facilitates the integration of such schemes into modern digital substations which are a staple of smart grids. Functional features of the architecture also offer powerful means of de-risking schemes and flexible implementation through self-contained modules that are suitable for reuse. An example adaptive distance protection scheme is presented and tested to demonstrate how the architecture can be implemented and to highlight the architecture's novel features.
