标准范围

IEC TS 62898-3-1:20 20（E）为微电网故障保护和动态控制的规范提供了指南。微电网中的保护和动态控制旨在确保微电网在故障和扰动条件下的安全稳定运行。本文件适用于包括单相或三相网络或两者的交流微电网。它包括与上游配电网单点连接（POC）的隔离微电网和非隔离微电网。它不适用于与上游配电网有两个或多个连接点的微电网，尽管此类系统可以遵循本文档中给出的指南。本文件适用于低压或中压或两者兼而有之的微电网。由于DC系统的特殊特性（极大的故障电流和没有自然发生的电流过零），DC和混合AC/DC微电网被排除在范围之外。本文件明确了微电网的保护和动态控制原则、通用技术要求以及故障保护和动态控制的具体技术要求。它解决了微电网保护要求、微电网暂态扰动控制和动态扰动控制要求方面的新挑战。重点介绍了常规电力系统保护与微电网保护功能新的可能解决方案之间的差异。根据具体情况，微电网运营商可以与配电系统运营商（DSO）协调定义额外或更严格的要求。本文档不涉及主动配电系统的保护和动态控制。本文件不涵盖测量继电器和保护设备的产品要求。本文件不涵盖低压电气装置的安全方面，IEC 60364（与低压电气装置相关的所有部分和修订）涵盖了这些方面。与低压微电网相关的要求可以在IEC 60364-8-2中找到。

IEC TS 62898-3-1:2020(E) provides guidelines for the specification of fault protection and dynamic control in microgrids. Protection and dynamic control in a microgrid are intended to ensure safe and stable operation of the microgrid under fault and disturbance conditions.
This document applies to AC microgrids comprising single or three-phase networks or both. It includes both isolated microgrids and non-isolated microgrids with a single point of connection (POC) to the upstream distribution network. It does not apply to microgrids with two or more points of connection to the upstream distribution network, although such systems can follow the guidelines given in this document. This document applies to microgrids operating at LV or MV or both. DC and hybrid AC/DC microgrids are excluded from the scope, due to the particular characteristics of DC systems (extremely large fault currents and the absence of naturally occurring current zero crossings).
This document defines the principles of protection and dynamic control for microgrids, general technical requirements, and specific technical requirements of fault protection and dynamic control. It addresses new challenges in microgrid protection requirements, transient disturbance control and dynamic disturbance control requirements for microgrids. It focuses on the differences between conventional power system protection and new possible solutions for microgrid protection functions.
Depending on specific situations, additional or stricter requirements can be defined by the microgrid operator in coordination with the distribution system operator (DSO).
This document does not cover protection and dynamic control of active distribution systems. This document does not cover product requirements for measuring relays and protection equipment.
This document does not cover safety aspects in low voltage electrical installations, which are covered by IEC 60364 (all parts and amendments related to low-voltage electrical installations). Requirements relating to low voltage microgrids can be found in IEC 60364-8-2.
