Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] Such as figure 1 As shown, the data monitoring method of the present invention involves the following architecture:

[0022] Inverter: The inverter is connected to the network device, and the blockchain client is implanted in the inverter. The blockchain client is implemented based on web3.js or web3j. The blockchain client inverter is equipped with wifi or The mobile communication module communicates with the State Grid and is connected to the grid to collect power generation data of the power station.

[0023] Blockchain client: provide two interfaces for chain account initialization and power generation data uplink, complete account initialization, receive power generation information data collected by inverters, call smart contracts, and complete power generation data uplink.

[0024] Account system: After the inverter is powered on, the blockchain client start...

Abstract

The invention discloses a method for monitoring new energy photovoltaic power generation data on the basis of block chains. The method includes steps of 1, implanting block chain clients in inverters;2, mounting the inverters and allowing the inverters to access networks; 3, automatically starting the block chain clients after the inverters are powered on, detecting communication with block chainnetworks, determining whether chain accounts are available or not by means of detection and generating a chain account by means of automatic initialization if the chain accounts are not available; 4,collecting power generation data of photovoltaic power stations by the inverters, triggering data chain uploading interfaces of clients at regular time, calling intelligent contracts and carrying outdata chain uploading; 5, developing decentralization App (application) on the basis of web3.js, carrying out interactive communication with the block chain networks, calling block chain intelligent contracts and querying the real-time power generation data of the corresponding power stations by related information of equipment. The block chain clients are implemented on the basis of the web3.js or web3j, and inverters of the block chain clients are provided with wifi (wireless fidelity) or mobile communication modules.

Description

technical field [0001] The invention relates to the field of electricity monitoring of power stations, in particular to a method for monitoring electricity generation data of new energy photovoltaic power stations based on blockchain. Background technique [0002] In 2017, China's newly installed photovoltaic capacity was 53.06GW, a year-on-year increase of 53.62%, setting a new historical record. Among them, distributed photovoltaics experienced explosive growth, with newly installed capacity reaching 19.44GW, a year-on-year increase of 3.7 times, while household photovoltaics also experienced explosive growth. It has become a highlight of distributed photovoltaics. As of the end of 2017, there were more than 500,000 households across the country using photovoltaics, a year-on-year increase of about 2.5 times. [0003] There are more than 30 million roofs suitable for installing photovoltaics in the country, but currently only more than 500,000 households have installed the...
