Wide-area electric energy metering terminal for power retail market and grid-load interaction

Abstract

The invention provides a wide-area electric energy metering terminal for a competitive power retail market and a grid-load interaction mode. The wide-area electric energy metering terminal comprises acore processing unit, an alternating current acquisition unit, a remote dual-mode communication unit, a local dual-mode communication unit, a dual-satellite automatic positioning and clock synchronization unit, a display unit, a power supply unit and an interface unit. The remote dual-mode communication unit comprises an MCU processing unit, two data transmission units and a power supply, the power supply supplies power to the MCU processing unit and the two data transmission units, the two data transmission units are respectively connected to the MCU processing unit, and the two data transmission units are two independent wireless public network communication modules and are respectively connected with the core processing unit. The wide-area electric energy metering terminal is suitablefor a competitive electric power retail market and a grid-load interaction mode, and has the advantages of being high in environmental adaptability, good in online stability, reliable in data transmission and the like.

Description

technical field [0001] The invention relates to a wide-area electric energy metering terminal for adapting to the competitive electric power retail market and the network-load interaction mode. Background technique [0002] The energy meter and acquisition terminal in the existing electricity consumption information collection system support four rates of "peak, peak, flat, and valley", and adopt the method of switching between fixed periods. The electricity in each rate period is uploaded to the metering system after calculation by the energy meter The master station conducts electricity bill settlement. This kind of fixed switching design of time period and rate, and the local setting mode of time period and rate parameters have been unable to meet the needs of diversified electricity sales package settlement in the electricity sales market. The main problems are as follows: [0003] First, the current energy meter and collection terminal can only meet the settlement nee...
