Small hydropower real-time power upload device and data processing method based on raspberry pie

Abstract

The invention discloses a small hydropower real-time power upload device and a data processing method based on a raspberry pie, which includes a power, voltage, current and power factor transmitter of a small hydropower station, and is characterized in that: power, voltage, current and power of a small hydropower station The power factor transmitter is connected to the wire of the analog-to-digital converter, the analog-to-digital converter is connected to the wire of the Raspberry Pi computer, the computer of the Raspberry Pi is wirelessly connected to the small hydropower prediction system on the ground regulation side, and the small hydropower power prediction system on the ground regulation side passes through The EMS is connected to the small hydropower power forecasting system on the central dispatching side; it solves the problem in the prior art that most of the small hydropower stations are located in remote areas, do not have wired network communication conditions, have poor real-time performance, and some small hydropower stations are unattended or report data is not available It can meet the technical problems such as the requirement of scheduling power prediction time interval.

Description

technical field [0001] The invention belongs to small hydropower real-time power upload technology, in particular to a small hydropower real-time power upload device and data processing method based on Raspberry Pi. Background technique [0002] Most of the small hydropower plants are located in remote areas and are distributed in large numbers along the river basins. Their power generation capacity is affected by various factors such as seasons, climate, and geographical environment, and has obvious cumulative effects and lag effects. Therefore, the output power often presents a large imbalance and Uncertainty. When there is large-scale small hydropower in a certain area, there will be a short-term surge of hydropower power caused by precipitation. When it is transmitted to the main network, if the dispatcher does not grasp this information, the control means will not be timely. and security are at the forefront of threats. The collection of real-time power of small hydro...
