摘要：

将现有配电网设备进行配电自动化改造可以显著提升配电网可靠性,配电自动化投资时寻求配电网可靠性提升和改造经济性之间的最佳平衡是需要解决的关键问题。提出了一种基于时间Petri网的配电自动化投资策略,通过建立配电网的时间Petri网模块化模型应用于配电网供电可靠性计算,并采用单位供电可靠性提升成本最低原则保证配电自动化投资的经济性,相关算例验证了所用模型的有效性。此方法在保证供电可靠性的基础上提高了配电自动化投资的经济性,为供电公司进行配电网规划及技术改造提供了参考。

Abstract:

Distribution automation transformation of existing distribution network equipment can improve the reliability of distribution networks. Seeking the best balance between the reliability improvement of the distribution network and the economy of transformation is a key problem to be solved in the investment of distribution automation. This paper proposes a distribution automation investment strategy based on a time Petri net, establishes a modular time Petri net model of the distribution network, and applies the principle of improving the unit power supply reliability of the distribution network and minimizing the cost to ensure the economy of distribution automation investment. The effectiveness of the proposed model is verified using relevant examples. The proposed method improves the economy of investment by ensuring the improvement of power supply reliability, and provides a reference for distribution network planning and the technical transformation of power supply companies.

Key words: distribution network, reliability, timed Petri nets, distribution automation, investment strategy
