互联电力系统的设计指南

[中文适用范围]： 本技术报告的主要目的是为互联电力系统（IPS）的规划和设计提供指南，从而实现可靠供电服务的交付。本文件中关于互联电力系统设计的指南将增强系统可靠性，减轻与系统大部分故障或意外分离相关的许多不利影响，并且不会因为正常设计意外而产生后果。 在本文技术报告的上下文中，互联电力系统指的是一个实体（控制区域或系统运营商）的高压传输系统，该系统可能因自身区域内的故障和扰动对其他连接系统产生不利影响。对于大面积区域，系统运营商可以定义其区域的一个子集，以将不利影响限制在其系统的较小部分内。 本技术报告规定了确保IPS高可靠性的推荐技术。一般来说，互联电力系统通过同步连接或通过直流互连异步连接。本文件旨在确保互连在两端一致地设计和运行。建议包括设计和操作要求，以承受本文件中规定的主要意外情况。 建议每个实体确保其高压IPS部分的设计和操作与这些指南一致。建议采取这一预防措施，否则额外的系统互连可能对连接实体的可靠性产生重大不利影响。还鼓励每个实体利用委员会、工作组、区域间研究和其他方法，以确保其IPS不断更新/增强和维护，以符合这些指南。 注：本指南适用于高压传输系统（通常超过60kV）。然而，某些系统条件（如低频负载削减（UFLSh））的缓解措施经常需要用于低压配电系统；因此，对于本传输指南的目的，互联控制区域和/或系统运营商可以根据需要建立电压水平。此外，本文件中的设计指南仅适用于IPS的那些元素（不是整个高压传输系统），这些元素可能因区域或大区域预定义子集内的故障和扰动对其他连接系统产生不利影响。本文件还提供了确定IPS这些元素的指南。 [外文原描述]： IEC TR 62511:2014(E) provides guidelines in planning and design of the interconnected power system (IPS) and consequently achieve the delivery of reliable supply service. The guidelines for the design of interconnected power systems within this document will enhance system reliability, mitigate many of the adverse impacts associated with the loss of a major portion of the system or unintentional separation of a major portion of the system, and will not be consequential because of normal design contingencies. In the context of this Technical Report, interconnected power system means an entity's (control area or a system operator) high-voltage transmission system that can adversely impact other connected systems due to faults and disturbances within its area. In the case of large areas, the system operator may define a subset of its area to keep the adverse impact contained within a smaller portion of its system. This Technical Report specifies the recommended techniques for securing an IPS to ensure a high level of reliability. Generally, interconnected power systems are synchronously connected or asynchronously connected through DC interconnections. This document aims to ensure that the interconnections are designed and operated consistently on both ends. The recommendations include design and operation requirements to withstand the primary contingencies specified in this document.
