摘要(Abstract):
随着配电网新设备、新技术应用不断向物理-信息融合方向发展,配电网形态也在发生快速变化,因此,需开展新装备、新技术适应性测试和实证,以提升配电网可靠性和资源调控能力。为此,对智能配电网真型试验建设和应用进行了研究。首先分析平台设计目的和系统组成,然后对电源及中性点试验平台、中压交直流网架试验平台、配电电缆及通道试验平台等平台的具体实现方法进行介绍,最后设计了10 kV一二次融合断路器接地功能试验、全自动智能型FA功能考核试验和低压台区故障感知试验三大试验场景。智能配电网真型试验平台的应用可解决配电网新技术设备传统检测方法不够全面的难题。
New equipment and technical applications on distribution networks demonstrate a tendency of physical data integration, and distribution network morphology is also changing rapidly. Therefore, adaptability testing and verification on new equipment and technology are required to improve distribution network reliability and resource scheduling capability. To this end, the construction and application of real tests for intelligent distribution networks are studied. Firstly, the purpose of the platform and system composition are analyzed. Secondly, the specific implementation methods of power, neutral point test platform, medium-voltage AC/DC architecture test platform, distribution cables, channel test platform, and other platforms are introduced. Finally, three major test scenarios are designed: earthing test 10 kV primary and secondary fusion circuit breaker, functional assessment test on intelligent fully automatic FA, and fault sensing test on low-voltage transformer area. The true test platform for intelligent distribution networks is applied to make up for the deficiency of the traditional testing methods for distribution networks and equipment.
