摘 要
随着电力系统的快速发展，配电网自动化已成为保障电网安全、可靠运行的重要手段。配电网自动化是指通过集成先进的计算机技术、自动控制技术、现代电子技术、通信技术及网络技术，实现配电网的实时监控、保护、控制和配电管理。配电网自动化的技术架构由系统组成、硬件架构、软件架构和功能集成四部分组成。系统组成包括配电主站、配电子站、配电终端和通信通道；硬件架构注重设备的稳定性和可扩展性；软件架构基于SOA构架，满足多业务需求；功能集成则实现了对配电网的全面监控和管理。在配电网自动化的故障诊断方面，存在多种方法，如故障电流法、专家系统法和人工神经网络法。这些方法的应用为配电网故障的快速定位和处理提供了有力支持。然而，配电网自动化在故障诊断中也面临着诸多挑战，包括功能设计单一、设备不兼容、系统结构设计不合理和管理机制不完善等。为解决这些问题，需要优化功能设计，提高旧设备兼容性，优化通信通道，并完善管理制度。配电网自动化在提高电网运行效率、降低故障率方面发挥着重要作用。面对挑战，我们应积极采取措施，推动配电网自动化技术的持续发展和应用。

Abstract
With the rapid development of the power system, distribution network automation has become an important means to ensure the safe and reliable operation of the power grid. Distribution network automation refers to the integration of advanced computer technology, automatic control technology, modern electronic technology, communication technology, and network technology to achieve real-time monitoring, protection, control, and distribution management of the distribution network. The technical architecture of distribution network automation consists of four parts: system composition, hardware architecture, software architecture, and functional integration. The system consists of a distribution main station, distribution electronic station, distribution terminals, and communication channels; The hardware architecture emphasizes the stability and scalability of devices; The software architecture is based on SOA architecture, meeting multiple business requirements; Functional integration enables comprehensive monitoring and management of the distribution network. There are various methods for fault diagnosis in distribution network automation, such as fault current method, expert system method, and artificial neural network method. The application of these methods provides strong support for the rapid localization and handling of faults in distribution networks. However, distribution network automation also faces many challenges in fault diagnosis, including single functional design, incompatible equipment, unreasonable system structure design, and imperfect management mechanisms. To address these issues, it is necessary to optimize functional design, improve compatibility with old devices, optimize communication channels, and improve management systems. Distribution network automation plays an important role in improving the efficiency of power grid operation and reducing failure rates. Faced with challenges, we should actively take measures to promote the sustainable development and application of distribution network automation technology.
