本文探讨了广域自动控制系统在配电网中的应用。今天，只有一小部分配电馈线采用广域控制策略。然而，随着配电工程师和管理人员对系统可靠性的关注，这一数字正在增长。随着“婴儿潮一代”向退休过渡，面对即将到来的电气专业知识短缺，配电网络的复杂性越来越大。在这种不断变化的环境中，广域自动控制有望提高系统的可靠性。本文介绍了广域自动控制策略，并讨论了对系统运行和系统保护实践的潜在影响。本文涉及的主题包括：1.配电网广域自动化控制策略综述。本概述介绍了自动网络重构在从电气故障中恢复、提供负载平衡以及协助电压/无功优化方面的目标和基本工作原理。2.对系统保护实践的影响。本节讨论广域控制系统的存在如何影响配电系统的保护。3.对系统操作实践的影响。本部分讨论了广域控制系统的存在如何影响配电系统的运行。将提出解决广域自动控制系统引入的潜在操作和保护挑战的建议。
This paper examines the use of wide-area automatic control systems in electric power distribution networks. Today only a small percentage of distribution feeders employ wide-area control strategies. However, this number is growing as distribution engineers and managers respond to concerns about system reliability. Distribution networks are growing in complexity in the face of a coming shortage of electrical expertise as the “baby-boom generation” transitions into retirement. In this changing environment, wide-area automatic control holds the promise of increased system reliability. This paper presents wide-area automatic control strategies and discusses the potential impacts on system operations and system protection practices. Topics covered in this paper include: 1. An overview of wide-area automatic control strategies for distribution networks. This overview presents the objectives and basic operating principles of automatic network reconfiguration in recovering from electrical faults, providing load balancing, and assisting with voltage/VAR optimization. 2. The impact on system protection practices. This section discusses how the presence of wide-area control systems affects the protection of the distribution system. 3. The impact on system operation practices. This portion discusses how the operation of the distribution system is affected by the presence of wide-area control systems. Recommendations will be presented that address potential operations and protection challenges introduced by wide-area automatic control systems.
