Power transmission and transformation equipment state quantity collection and storage method and system

Abstract

The invention discloses a power transmission and transformation equipment state quantity collection and storage method and a system. The method comprises the steps: employing a temporary chain layer to store power transmission and transformation equipment field state quantity data after feature marking, carrying out the matching with a state quantity result generated by a state quantity manager node layer, and obtaining the power transmission and transformation equipment field state quantity data through the state quantity manager node layer, the state quantity manager node layer performs characteristic marking on the collected field state quantity data of the power transmission and transformation equipment and then transmits the field state quantity data to the temporary chain layer for temporary storage, and the state quantity manager node layer performs state quantity judgment on the power transmission and transformation equipment according to the collected field state quantity data of the power transmission and transformation equipment; the state quantity result and the power transmission and transformation equipment field state quantity data corresponding to the state quantity result and stored in the temporary chain layer are transmitted to the main chain layer, so that interactive calculation of a large amount of data in the main chain layer is avoided. The calculation load of the main chain layer is effectively reduced, efficient power transmission and transformation equipment state quantity data transaction activities are supported. The data processing capability is improved.

Description

technical field [0001] The invention belongs to the operation and maintenance technology of power transmission and transformation equipment, and in particular relates to a method and system for collecting and storing state quantities of power transmission and transformation equipment. Background technique [0002] The power grid is an important infrastructure for the safe and stable operation of the national economy. Power transmission and transformation are important functions of the power grid. It is very necessary to monitor the data of power equipment in real time to avoid irreversible failures.

Problems solved by technology

Some malicious nodes can eliminate user asymmetry by analyzing and classifying transactions in the blockchain, thereby endangering user privacy

Finally, the data manager node may impose a high load on the network, for example, collecting data from the underlying power transmission and transformation equipment every minute, overwhelming the network

Transmitting such a large volume of data requires a large amount of bandwidth at the decentralized power transmission and transformation equipment end, which may not be scalable in a smart grid with millions of equipment

Furthermore, most devices in the smart grid have limited resources, so generating such a huge volume of data transactions may be beyond their capabilities
