An intelligent detection and processing method of electric energy acquisition data based on Beidou satellite communication technology

Abstract

The invention discloses a Beidou satellite communication technology-based method for intelligently detecting and processing acquired electric energy data. According to the method, the current actual value of the acquired electric energy data of a Beidou satellite is compared with a historical value and an integral electric quantity, and then wrong data caused by the distortion during the transmission process can be automatically identified and processed. If the current actual value is larger than the historical value, the interval time and the difference value between the current actual value and the historical value are further calculated. Meanwhile, the reasonable quantity of generated electric energy within the difference value and the interval time is compared with the integral electric quantity. After that, whether the anomaly of data jump caused by the distortion during the transmission process occurs to the current actual value or not can be judged. According to the technical scheme of the invention, the intelligent detecting and handling problem of abnormal data during the transmission process of the acquired electric energy data of the Beidou satellite to a scheduling main station via a satellite channel can be solved. Meanwhile, the related alarm function for suspicious data is provided at the same time, so that the operation and maintenance personnel can check the data in the timely manner. The operation and maintenance efficiency is improved, while the accuracy and the availability of the acquired data of the Beidou satellite are significantly increased at the same time.

Description

technical field [0001] The invention relates to the technical field of power grid electric energy data transmission, in particular to an intelligent detection and processing method for electric energy collection data based on Beidou satellite communication technology. Background technique [0002] At present, there are 567 non-statized small power generation enterprises in Anhui Province, with a total installed capacity of 2128MW, accounting for 8% of the total installed capacity of the society, which is equivalent to two large power plants with an installed capacity of one million. The total power generation capacity cannot be underestimated. Most of these non-scheduled power plants do not have the conditions to communicate with the power control center. The control center lacks real-time dispatch and management means for such small power generation enterprises, which is not conducive to the rational deployment of energy and increases power consumption. [0003] Based on Be...

Problems solved by technology

By adopting the communication method of Beidou satellite channel, it solves the problems of no signal in wireless transmission and high cost of laying dedicated lines in many areas for accessing non-systematic power plants.

Install the data acquisition terminal and Beidou user machine at the non-unified control power plant, and send the data to the Beidou satellite command plane through the Beidou satellite. However, when the data is transmitted through the Beidou satellite channel, it may be caused by signal strength, weather, channel quality, etc. The occurrence of problems such as frame loss and error frames will lead to the distortion of the data received by the dispatching master station, which will seriously affect the accuracy and availability of power energy collection data, and even cause serious problems such as negative numbers and large numbers in power energy statistics. The abnormal situation also restricts the deepening application of Beidou satellite communication technology in the electric power field to a certain extent
