Large-scale access oriented distributed photovoltaic remote data collection system architecture method

Abstract

The invention discloses a large-scale access oriented distributed photovoltaic remote data collection system architecture method, comprising the step of carrying out architecture on an on-site collection terminal, a transmission rule and a collection server side of a remote data collection system. An IP address of the collection server side is fixed. The on-site collection terminal communicates with the collection server side by configuring the transmission rule. According to the transmission rule, a transmission method based on Webservice is employed, and normal data submission, data retransmission and time check service are finished by configuring transmission parameters. According to the method provided by the invention, the access more than thousands of distributed photovoltaic power stations can be supported, the access of millions of measurement points can be supported, the access of the photovoltaic power stations of a province / city region can be covered comprehensively, and an time interval of transmitting real-time data by the system can be set according to a demand. According to the data collection system provided by the invention, all real-time data collection service of the photovoltaic power stations of the region can be provided for a regional power grid, the support for follow-up data analysis and evaluation is provided, the operation characteristics of the accessing photovoltaic power stations can be grasped by the power grid comprehensively, the plan and design of the power grid are optimized, and the new energy consumption and absorption capability of the power grid is improved.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation, and relates to a large-scale access-oriented distributed photovoltaic remote data acquisition system architecture method. Background technique [0002] In recent years, my country's solar photovoltaic power generation application field has achieved rapid development. According to public information, my country's new grid-connected photovoltaic installed capacity in the first half of 2016 was about 22.5GW, of which about 11.3GW was added in June alone. While the installed capacity is growing rapidly, due to the explosive growth of installed capacity in the early stage, the development space of centralized photovoltaic power plants is restricted by factors such as the limitation of power grid consumption capacity and land shortage. Distributed photovoltaics will surely achieve further development during the "13th Five-Year Plan" period due to its proximity to the load center, go...

Problems solved by technology

[0006] At present, the communication between the existing remote data acquisition system of photovoltaic power station and each distributed photovoltaic power station mainly adopts the traditional power communication protocol, and its data acquisition is easily affected by the unstable connection of the public network. Due to the limitations of the above-mentioned data acquisition system, the data reliability and integrity of the operation and maintenance based on data acquisition or the remote data center become poor, which affects the operation and maintenance or remote monitoring system. run correctly
