Problems solved by technology

[0002] Protection equipment is often used in power systems, but the current protection equipment basically does not have the ability of logic analysis and data analysis, making the protection logic unclear and intangible
When there is a problem on site and the protection does not move as expected or even does not move, it often makes some inexperienced engineers unable to start
In addition, some sites are equipped with fault recording devices, but the fault recording devices only record the changes of electrical quantities before and after a fault occurs, but they are powerless for some abnormal situations that are not faults, such as analyzing whether there is a problem in the motor startup process Wait

Embodiment Construction

[0035] In order to clarify the technical scheme and technical purpose of the present invention, the present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0036] like figure 1 The shown power protection device is an example, and the power protection device includes a CPU (central processing unit) and components such as an LCD display, an input keyboard, and a FLASH flash memory connected to the CPU respectively, and the CPU communicates with the background computer system through a communication interface connect.

[0037] figure 1 Among them, the current and voltage signals are connected to the AD conversion circuit module of the CPU through the conditioning circuit and the filter circuit, and the CPU converts the analog signals of the current and voltage into digital signals through AD conversion. These input current and voltage signals generally include A\B in the power system \C Current signal, measure...

Abstract

The invention discloses a data recording and analysis method adopted in a power protection device. The data recording and analysis method comprises the steps of signal acquisition, data channel configuration, trigger source and trigger condition setting, capture of recorded target data, background analysis and the like, helps an engineer to record data required to be recorded, including analog quantity signals, switching volume signals, intermediate quantity signals and various signal data produced in a power system or produced by the protection device, can be used for monitoring and analysis of the power system in the daily running process, is not limited by data before and after faults occur, and facilitates analysis on various power system problems or a system running state, performed by the engineer at any time. In addition, the data recording and analysis method is easy to achieve and facilitates quick accumulation of work experience.

Description

technical field [0001] The invention belongs to the technical field of electric power protection, and specifically relates to a method for recording and analyzing data in a power protection device Background technique [0002] Protection equipment is often used in power systems, but the current protection equipment basically does not have the ability of logic analysis and data analysis, making the protection logic unclear and intangible. When a problem occurs on site and the protection does not move as expected or even does not move, it often makes some inexperienced engineers unable to start. In addition, some sites are equipped with fault recording devices, but the fault recording devices only record the changes of electrical quantities before and after a fault occurs, but they are powerless for some abnormal situations that are not faults, such as analyzing whether there is a problem in the motor startup process Wait. Contents of the invention [0003] Aiming at the p...
