Comprehensive measurement and regulation-control apparatus and method for active power distribution network

Abstract

The invention provides a comprehensive measurement and regulation-control apparatus and method for an active power distribution network. The comprehensive measurement and regulation-control apparatus comprises a main board and a power supply mechanism, wherein the main board comprises a comprehensive decision plugin, an intelligent alternating current sampling plugin which is used for being connected with a current transformer on an outgoing feeder line for collecting the load current of the circuit, and used for being connected with a voltage transformer on a power supply bus for sampling the voltage information of the bus, an intelligent I/O plugin which is used for being connected with a control switch on the outgoing feeder line for sampling signals of various kinds of electrical hard contacts of the active power distribution network, a multifunctional communication plugin which is used for being connected with peripheral equipment and an intelligent power supply plugin.

Description

technical field [0001] The invention relates to the field of electric power engineering automation, in particular to a device and method for comprehensive measurement and control of an active distribution network. Background technique [0002] In order to solve the increasingly serious global energy crisis and reduce carbon emissions, the core of the current national energy strategy is to use clean energy to replace the consumption of fossil energy such as coal and oil, in order to achieve harmonious economic and social development, and gradually promote the adoption of various new energy sources. With the penetration and access of various distributed energy sources and the wide application of electric vehicles and energy storage equipment, the structure of the distribution network has undergone major changes. Interactive active distribution network is the development trend of future distribution network. Different from traditional distribution network, the core concept of ...

Problems solved by technology

The existing advanced metering (AMI) and automatic meter reading (AMR) technologies focus on the collection of electric energy information and the active power consumption adjustment on the user side based on the ladder price information, in order to guide the orderly power consumption of the user end and reduce energy consumption. It has a positive effect, but there are deficiencies in the active distribution network that requires real-time interaction between the source network and the load. For example, it cannot comprehensively analyze and utilize meteorological information that has an important impact on the output of distributed power generation, and cannot perform local-level distributed power generation. Power forecasting, coordinated control of flexible loads (controllable loads and interruptible loads) and guidance on power consumption
