Abstract

The invention discloses a data processing device and method for power quality monitoring data in a station area, which acquires original sampling data and buffers the original sampling data, and the original sampling data is signal conditioning for three-phase voltage signals and three-phase current signals and the data obtained after calculation; calculate the original sampling data to obtain the frequency calculation result; according to the frequency calculation result, perform signal extraction on the original data stored in the data buffer area to obtain a complete cycle signal, which is used for power quality monitoring Calculation of steady-state data and determination of transient events in power quality monitoring. The invention processes the original data and extracts and applies the complete cycle signal, and realizes the calculation of the steady-state data of the power quality monitoring in the station area and the judgment of the transient state event. It can reduce the cost of hardware, and at the same time support metering (measurement and control) and power quality monitoring business applications in the station area, and meet the special requirements of power quality monitoring for data quality.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data processing device and method for power quality monitoring data in station areas. Background technique [0002] With the massive addition of distributed power sources, micro-grids, electric vehicles, electric heating, and low-voltage inverters to the power grid, power quality problems in distribution stations have become more prominent, including: frequent voltage fluctuations caused by power fluctuations, and three-phase power caused by bidirectional flow of single-phase power. The aggravation of phase imbalance and broadband resonance problems caused by a large number of rectifier and inverter devices have seriously affected the quality of power supply services, making the current academic and industrial circles pay close attention to the power quality of distribution stations. [0003] The power quality monitoring business has specific requirements for data quali...
