Problems solved by technology

All on-site data collection information needs to be collected on-site and communicated to the main station system for decision-making. The multi-agent intelligent decision-making system performs data processing and decision-making analysis in a unified way. This system structure has the following problems: the workload of the on-site communication access of the main station system Large, various heterogeneous communication methods lead to complex data pre-access protocols; information modeling is not uniform, and secondary mapping is required; at the same time, network communica

Abstract

The invention provides an active power distribution network data collection system and method. The system comprises at least one terminal-type intelligent agent arranged and deployed at an electrical terminal of an active power distribution network, and at least one hub-type intelligent agent for connecting the terminal-type intelligent agent, wherein the terminal-type intelligent agent at least comprises a series interface for connecting a low-speed narrowband device, a network interface for connecting a sensor network and an IEC104 communication protocol interface for connecting the hub-type intelligent agent; the series interface and the network interface work under a communication service framework; the hub-type intelligent agent at least comprises the IEC104 communication protocol interface for connecting the terminal-type intelligent agent, and an IEC61850 communication protocol interface; and the IEC61850 communication protocol interface is applied to other hub-type intelligent agents.

Description

technical field [0001] The invention relates to the field of relay protection automation of electric power engineering, in particular to an active distribution network data acquisition system and method suitable for hierarchical multi-agent decision-making. Background technique [0002] The highly permeable active distribution network of distributed power sources realizes higher reliability and quality of power supply through the real-time interaction of "source (power supply), network (distribution network), and load (load)" and improves energy efficiency. utilization efficiency. Multi-power supply coordination can effectively solve problems such as insufficient regional power transmission and distribution capacity, and ensure stable and reliable operation of the power grid; it can also effectively shift peaks and fill valleys, accurately control loads, and reduce system failure rates. [0003] Different from the traditional distribution network, the comprehensive measurem...
