solution overview

with the advancement of national power market reforms, the scale of power market transactions is continuously expanding. the pilot program for the spot market is being accelerated, the medium- and long-term power trading mechanisms are being continuously improved, and the market-based mechanisms for the consumption of clean energy are becoming increasingly diversified. inter-provincial transactions, intra-provincial transactions, medium- and long-term transactions, and spot transactions are more efficiently coordinated and connected. in order to improve the lean management level of electricity metering at power plants, substations and other gateways of provincial and municipal power companies, a power company has launched the construction of a cross-provincial gateway metering bus balance management system.
the system utilizes internet of things (iot) technology to achieve minute-level high-frequency data collection from the power grid. it integrates various data through technologies such as big data platforms, data exchange platforms, and microservices, enabling multi-dimensional data fusion, massive data statistics, and cross-system analysis. the system employs svg graphics to provide visual monitoring of gateway metering, displaying the operational status of each plant and substation in real time, and offering convenient access to plant/substation equipment and data information at any time.

solution highlights

1. building multi-channel communication technology based on asynchronous interaction technology to achieve high-concurrency collection and verification of massive data
the system technically achieves minute-level collection of 22 operational data items from power meters at substations/gateways. it employs distributed task scheduling and business collaboration methods for real-time electricity amount data collection and verification, ensuring data timeliness and accuracy. through high-speed data transmission, the electricity amount data is delivered to various data analysis layers for modeling and visualization, thereby better supporting user business operations.
