标准摘要
[中文适用范围]: 本部分 IEC 62786 作为技术规范,提供了分布式能源资源(DER)连接到电力网络(以下简称“网络”)的原则和通用技术要求。它适用于 DER 与网络的规划、设计、运行和连接。内容包括通用要求、连接方案、开关设备选择、正常运行范围、抗扰动能力、频率偏差有功功率响应、电压变化无功功率响应、电磁兼容性和电能质量、接口保护、连接和启动发电、有功功率管理、监控、控制和通信以及一致性测试。它由 IEC 62786 系列的补充部分进行补充,涵盖特定方面。本文件规定了 DER 连接到额定频率为 50 Hz 或 60 Hz 的网络的接口和互操作性要求。这些要求旨在应用于 DER 与电网的连接点(POC)。在某些情况下,这些要求可应用于发电机的交流端。IEC 62786 的补充部分提供了更具体的要求。DER 包括连接到中压(MV)或低压(LV)网络的分布式发电和电能存储,形式包括同步发电机、异步发电机、电力变流器等。 [外文原描述]: IEC TS 62786-1:2023, which is a Technical Specification, provides principles and general technical requirements for distributed energy resources (DER) connected to an electric power network (in the following: the "network"). It applies to the planning, design, operation and connection of DER to networks. It includes general requirements, connection scheme, choice of switchgear, normal operating range, immunity to disturbances, active power response to frequency deviations, reactive power response to voltage changes, EMC and power quality, interface protection, connection and start to generate electrical power, active power management, monitoring, control and communication, and conformance tests. It is supplemented by additional parts of IEC 62786 series, covering specific aspects. This document specifies interface and interoperability requirements for connection of DER to a network operating at a nominal frequency of 50 Hz or 60 Hz. These requirements are intended for application at the point of connection (POC) of the DER to the grid. In some situations, the requirements can be the applied at the AC terminals of the generator. Additional parts of IEC 62786 provide more specific requirements. DER include distributed generation and electrical energy storage in the form of synchronous generators, asynchronous generators, power converters, etc., connected to the medium voltage (MV) or low voltage (LV) network.
