Abstract

A kind of fault detection oscilloscope device and method for the quality of power and the electrical system are disclosed, which belongs to the field of detection technique of electric system, and it includes three subsystems: detection oscilloscope subsystem, remote-control monitor subsystem, and time setting subsystem; the oscilloscope subsystem can do multi-point diagnosis for electric system, and detects and records the quality parameters of power; the remote-control monitor subsystem consists of precedence sever and Internet client, and it can realize the double action that transmitting fault information and monitoring the daily running of protective and safe device; the time setting subsystem provides the system time and insures the time synchronization with system; the realizing method includes dynamic parameter measurement, fault time division; starting criterion, fault oscilloscope, uploading record, and remote-control command procession. The invention realizes the digitalization, network, intelligent, and integration of detection oscilloscope device, and it can improve the quality of power, ensure the equipment running safely and steadily.

Description

technical field

[0001] The invention belongs to the technical field of power system detection. Background technique

[0002] The existing power quality and power system fault detection basically adopt the products of the 1990s. Most of these wave recorders are converted from the structure of microcomputer relay protection devices, using analog-to-digital converters with a resolution of 12 bits or lower. Bit single-chip microcomputer, on-chip RAM capacity is also very small, communicate through serial port or parallel port. In recent years, DSP chip technology has developed rapidly, and with the rapid improvement of power system automation level, many performance indicators of the original fault recorder are obviously lagging behind, especially in high-speed fault recording and recording data analysis. behind.

[0003] The power fault recorders in the 1990s were basically microcomputer devices that worked independently, and their internal storage devices needed to be backe...
