Substation lightning arrester data synchronous acquisition and transmission equipment and control method thereof

Abstract

Provided are substation lightning arrester data synchronous acquisition and transmission equipment and a control method thereof, which relate to the technical field of substation lightning arrester running state data acquisition and transmission and especially relate to the intelligent substation lightning arrester running state data synchronous acquisition and transmission technology. The substation lightning arrester data synchronous acquisition and transmission equipment comprises a sensor module, a signal processing module and a ZigBee wireless transmission module. The sensor module is formed by a Hall current sensor wounded by a coil; the sensor module transmits the collected voltage and current signals of a lightning arrester to the signal processing module; and after being amplified by a power amplifier in the signal processing module, the voltage and current signals are transmitted to an upper computer in a monitoring center through the ZigBee wireless transmission module. The signal processing module comprises a multichannel AD and conditioning circuit module, a clock synchronization module, a high-speed CPLD module, a DSP module, an IEC61850-9-2 protocol processing module, other types of protocol processing modules and an FPGA module.

Description

technical field [0001] The invention relates to a substation arrester data synchronization acquisition and transmission device and a control method thereof, which relate to the technical field of data acquisition, conversion and transmission of the substation arrester operating state, and in particular to a technology for intelligent substation arrester operation state synchronization information acquisition and transmission. Background technique [0002] At present, in the process of realizing the synchronous acquisition and transmission technology of on-line monitoring of arresters in substations, the signal processing of the back-end is gradually being paid attention to by the majority of electric power workers. The development of signal processing technology will lead to more accurate and effective monitoring results, and also put forward higher requirements for the online monitoring device of the arrester in the front section. The existing results show that the current ...

AI Technical Summary

Problems solved by technology

The existing results show that the current online monitoring devices generally face problems such as poor synchronization of signal acquisition, slow transmission speed or non-standard communication protocols.

The synchronization of signal acquisition is poor, which often brings great errors to the back-end signal processing

The non-standard communication protocol leads to non-uniform signal format, which brings more workload to the background signal processing, and there is also the problem of incompatibility with other automation equipment, and the applicability in the smart grid is also greatly reduced

Slow transmission speed will prolong the data acquisition time, which cannot keep up with the speed requirements of background signal processing
