标准范围

IEC TS 62786-41:2023(E)是一项技术规范，定义了用于控制分布式能源(DER)和连接到电力网络的负载的频率和频率测量变化率的最低要求。本文件规定了频率和频率测量变化率的特性，以评估其性能。它描述了频率和频率测量变化率的主要用例，以及相关的性能水平。它描述了评估指定特性的功能测试的原理，并定义了在稳态或动态条件下影响这些性能的影响因素。本文件定义了适用于DER或负载内部或外部的频率测量的频率和变化率的功能要求。在DER的情况下，本文件提供了IEC 62786的其他部分或相关IEC技术委员会制定的标准中定义的要求之外的要求（例如，TC 82用于光伏系统，TC 88用于风力系统，TC 120用于电能存储系统（EES））。本文件适用于分布式能源和负载，无论与电网连接点的电压水平如何。本文件未指定用于频率或频率变化率测量的硬件、软件或方法。它没有指定与硬件设备相关的环境条件（气候、3 kHz以上的电磁干扰、机械应力等）相关的测试。）.与时间戳相关的频率测量的频率和变化率不在本文档的范围内。IEC 60255 118 1已经涵盖了这些测量。与保护功能或保护继电器相关的频率测量的频率和变化率不在本文件的范围内。IEC 60255-181已经涵盖了这些要求。

IEC TS 62786-41:2023 (E), which is a Technical Specification, defines minimum requirements for frequency and rate of change of frequency measurements used to control distributed energy resources (DER) and loads connected to electrical power networks.
This document specifies the characteristics of frequency and rate of change of frequency measurements to evaluate their performances. It describes the main use cases of frequency and rate of change of frequency measurements, with associated level of performances. It describes the principle of functional tests to evaluate the specified characteristics and defines the influencing factors that affect these performances, under steady state or dynamic conditions.
This document defines the functional requirements applicable to frequency and rate of change of frequency measurements which can be inside or outside the DER or loads. In the case of DER, this document provides requirements additional to those which are defined in the other parts of IEC 62786 or standards produced by the relevant IEC technical committees (e.g. TC 82 for photovoltaic systems, TC 88 for wind systems, TC 120 for electrical energy storage systems (EES)).
This document is applicable to DER and loads regardless of the voltage level of the point of connection to the grid.
This document does not specify hardware, software or a method for frequency or rate of change of frequency measurement. It does not specify tests linked to environmental conditions associated with hardware devices (climatic, electromagnetic disturbances above 3 kHz, mechanical stress, etc.).
Frequency and rate of change of frequency measurements associated with time stamping are not in the scope of this document. These measurements are already covered by IEC 60255 118 1.
Frequency and rate of change of frequency measurements associated with protection functions or protection relays are not in the scope of this document. These requirements are already covered by IEC 60255-181.
