Electric energy metering system suitable for competitive retail markets

Abstract

The invention discloses an electric energy metering system suitable for a competitive retail market, and the system comprises: a user layer which is used for enabling an intelligent electric meter, auser portal website and an indoor controllable power utilization device of a user to be connected through a gateway, and presenting the real-time power utilization information of the user and the electricity price information transmitted by an electric power company to the user; an acquisition equipment layer which is used for enlarging the coverage area of the intelligent electric meter and the acquisition terminal as required; a remote communication layer which is used for transmitting the measurement information, the fault alarm information and the device interference alarm information readby the electric meter to a data center in real time by adopting a fixed bidirectional communication network; and a main station layer which is used for opening a power grid, an electricity selling company, a third-party service company and a user, so as to enable different main bodies to have different data access authorities. The system can realize efficient and accurate settlement of various retail packages and promote network load interaction, effectively reduces the complexity of user electric charge settlement, improves the practicability and flexibility of electric energy metering, andis simple and easy to realize.

Description

technical field [0001] The invention relates to the technical field of electric energy metering, in particular to an electric energy metering system adapted to a competitive retail market. Background technique [0002] At present, Xindian plans to further introduce competition by gradually liberalizing the electricity sales business, improve the operation mechanism of the electricity market, encourage more market players to participate in transactions, and give full play to the decisive role of the market in resource allocation. With the establishment of the spot market and the continuous liberalization of the retail market, the number of market players continues to increase, the transaction scale continues to increase, the transaction sequence is continuously refined, payment methods are more flexible, retail packages are more diverse, and users switch retailers more frequently. This increases the complexity of user electricity bill settlement, and accurate and timely elect...

[0005] (2) Variability requirements for rate period setting

The spot market usually adopts the "daily clearing and monthly settlement" settlement mode. Smart meters need to upload the user's time-sharing electricity consumption data with time stamp information every day. The traditional single RS-485, power carrier, low-power wireless and other local communications The method takes a long time, and it is possible that before the current round of transcription process of the terminal or concentrator is satisfied, the next round of energy transcription required for settlement has already been initiated, which will bring huge communication pressure to the energy metering system
