Foreword
Thank you for choosing the microcomputer dynamic recording analysis device that you have been carefully crafted by baedi electric limited. This technical instructions apply to the dynamic record analysis unit of the lbd-mgr-8000 micromachine generator transformer group。
Please read this note and keep it carefully for your maintenance, in the hope that it will greatly facilitate your work。
Technical use instructions for dynamic recording devices for the lbd-mgr-8000 micromanufacturing generator group dynamic recorders, version v. 2. 3
1 overview
The recording series, which have been in operation since 1996, has been successful in filling the gaps in the recording of aircraft in the country, with performance indicators that meet the operational requirements of the power system and are well received by a wide range of electricity users. Over the years, our company has been working to upgrade micro-facing video products, and with the rapid growth in domestic power demand and the increasing technical requirements for relay protection, the mere failure-recording data no longer meet the needs of users, and only dynamic recording data can more comprehensively monitor, record and analyse the performance of power systems。
A new generation of embedded dynamic record analysis units with autonomous intellectual property rights was designed and developed on the basis of the original micro-engineer failure-recording device. Full compliance with industry standards dl/t553-94, dl/t663-1999, dl/t 873-2004. The recording of electrical voltage, current data and movement sequences of protection and safety automatic devices, primarily used for power system failures or abnormal conditions, and the reproducing of electrical volume changes during malfunctions and unusual operations, as well as the completion of a comprehensive analysis of recorded data, provide a basis for determining the cause of failure, properly analysing and evaluating the behaviour of protection and automatic devices. This device is used primarily in fire power plants, hydropower plants, wind power generation and nuclear power plants。
Technical characteristics
2. 1 high performance embedded hardware structure platform design
The 32-bit floating-point dsp, which uses low-capacity, robust operational capacity, is responsible for sampling, completing the calculation of various start-up methods in a very short period of time to enable the device to determine failure quickly and accurately; and the etx embedded mainboard of the fan is responsible for data processing, which has micro-efficiency, stability, reliability, etc., and designs different i/o modes according to actual demand. This, together with large programmable logical devices, smd tablets, and six-storey pcb printing board applications, has greatly improved the stability and reliability of the devices. 2. 2 stable and efficient embedded software platform design
Using a real-time multi-task embedded operating system used internationally by the military, it could simplify programming, tailor it to actual needs, operate on very small embedded equipment, have small programs and take advantage of the limited computer resources. Embedded operating systems avoid malicious attacks on computer viruses and on the internet, thereby ensuring that the system is not damaged or paralysed by user error, viruses, etc. 2. 3 high-speed data collection
The maximum collection speed of this device is 20 khz, with a switch resolution of 0. 05 ms, which provides a high-quality data source for a full and detailed analysis of malfunctions, ranging and monitoring system operations; by analysing the micro-sections of observational data waves, it can help the operation maintenance staff to detect defects in the newly delivered equipment or hazards in obsolete equipment that has been in operation for many years to be repaired. It is extremely useful to discover the unusual state of the operating equipment for the exact re-emergence of the malfunctioning waveforms and for a true reflection of the quality of the power supply。
2. 4 humanized visual self-diagnostic chip level alert function
Owing to redundant design on hardware, it is possible to conduct a self-check of the main tablet chip on the plate and, if the chip is damaged, to report in situ the window visual display (e. G., failure of chips such as ad, sdram, fifo), avoiding defects that could not be maintained by the pre-mechanical failure maintenance staff in the event of network disruption or back-office failure; it is also possible to upload analysis stations or remote movements. 2. 5 independent operation free of security models
The device was designed with a back-plug 6-u box, which was robust in terms of interference resistance, installation, maintenance and debugging. Run independently, generate transport automatically
Lines, operating logs, detailing the operation of the device, so that the operation and operation of the recorder is documented. The device is equipped with a radiation-free, green screen tft lcd monitor, direct output display and wave-shaped analysis. It is also possible to use a manager to operate the device in its entirety through the network。

2. 6 steady, temporary data using independent dual-channel storage, transmission technology
The independent storage and transmission of steady and temporary data does not affect each other. The device has a dynamic recording function of variable length. That is, there is a steady-state recording function for the recording of normal operating data of the system, including electrical volumes such as voltage, current, power, powerlessness, frequency, etc., which is continuously recorded on non-facility start-up when the device is operational, even when the system has an abnormal or malfunctioning temporary data recording. It is ensured that in the event of repeated major disturbances (such as large-scale natural disasters such as system smoulders) occurring in the electrical grid over a continuous period of time, the device will be able to record the full process data for each major disturbance. 2. 7 large-volume data secure storage
The device is designed with advanced and reliable hardware, allowing the recording data to be stored directly on disks, so that the volume of the recording data is no longer affected by memory capacity, and now has a large capacity of storage media sufficient to meet the capacity for continuous recording; data security is not affected by network integrity and power failure. 2. 8 network function
Support for the tcp/ip communication agreement; support for the iec 870-5-103 communications regulation; support for the 100 gigabytes/gigae-ether network; support for dual winch lines, inter-axis cables, fibre-optics and multiple modes of communication for telephone lines; and ease of communication with the trouble information management system, dcs, sis, mis and other management system communication networks。
2. 9 generator, transformer electrical test function
Capable of conducting a magnetic machine air-loading test; a generator air-loading test; a generator short-circuit characterization test; a main magnetic load test when the generator is empty; a main magnetic load test when the generator is short-carrying; a generator's empty magnetic anti-magnetic test; a 10 per cent step response test for the magnetic system; an automatic zero-lifter test for the generator; a zero-lifter test for the main transformer; a network test during the same period; a custom test (other tests requested by the user); etc。
3 technical indicators
3. 1 maximum sampling frequency: 20 khz。
Model conversion accuracy: 16. Switch event resolution: 0. 05 ms. Harmonic resolution: 99. 3. 2 data recording modalities
The data recording of the device is divided into stable data records and temporary data records with absolute time marks. 3. 2. 1 recording of steady-state data
The devices keep track of critical electrical quantities of generators such as voltage, current, power power, powerlessness, frequency, etc. Data recording intervals may be 0. 02s and 1s. 3. 2. 2 provisional data recording 3. 2. 2. 1 mode of provisional data recording
The failure dynamic records data fractions a, b, c and d are recorded for continuous failure, and when the grid is heavily disturbed, the device automatically starts to enter the recording process and is recorded as follows。
Time a: the status data before the onset of the major disturbance, with a recording time of 40 to 500 ms, can be set by the user. B-time: post-disturbation state data, recording time from 100 to 10,000 ms, can be set by the user. Time c: status data after major disturbance, recording time 1-20 seconds can be set by the user。
D-time: 10 to 30 minutes of recording and 50/10/1 hz sampling frequency in case of system oscillation。
