Fault Recording Oscillograph

1. Application Scope

EDLB-601APortable waveform recorder utilizes advancedDSP Please provide the Chinese content to be translated.32 Positioned in the embedded fieldCPUIntegrating with a high-performance embedded real-time operating systemVxWorks An embedded power fault recording and analysis device designed to meet the development needs of the power system. It can be widely used in various voltage level lines and generators.-Transformer sets and transformers require fault wave recording and status logging for analysis.

2. Technical Features

1) Signal acquisition and startup calculations utilize a singleDSP Framework, by1 PieceDSP Achieve32 Road simulation quantity.32The integration of road switch quantities; simultaneously adopting a new circuit structure;75000 Our large-scale programmable logic devices feature high integration, strong anti-interference capabilities, and stable system operation.

2) 32 High-Speed Floating Point Digital Signal Processor(DSP)，16 No Chinese content provided, so the translation remains unchanged: "位"A/DSampling Rate10kHz Adjustable, Harmonic Resolution ≤99 Next, switch event resolution0.1ms；

3) Adopting a high-performance real-time embedded operating systemVxWorksThe system is stable, reliable, and offers excellent real-time performance.

4) Waveform Data Storage: Waveform data is stored separately32 PositionCPU Enhanced data security on the management platform.

5) Data recording implementedA-B-C Section MethodA、B、C The section entirely utilizes sampled values for recording, discarding the traditionalD、E Low sampling rates and effective value recording segments allow for all data to be subjected to phasor diagram analysis and impedance analysis, significantly enhancing data usability.

6) Supports long-duration continuous recording; the device can operate1KHz Continuous sampling values recorded, with data logged7 The data retention period is limited only by the number of channels and storage capacity, with a refresh cycle of the universe, eliminating the traditional slow-scan recording of effective values with one point per week.

7) Variable-length dynamic wave recording and fault location, with the distance measurement accuracy of metallic short-circuits superior to2%；

8) The criterion for initiating the recording is comprehensive, enabling sensitive start-up recording under various short-circuit, grounding faults, and other abnormal conditions.

9) Robust computational and analytical capabilities (amplitude, peak, RMS, and frequency calculations for voltage and current, active and reactive power calculations, power angle and phase angle measurements, phasor, sequence, and harmonic analysis).

10) The formula editor can generate waveform diagrams of various power and export quantities, allowing for dynamic observation of their time-based trajectories and accurately reproducing the entire process of a fault.

11) Supports various time synchronization methods, including contact pulse synchronization.IRIG-B Our products support time synchronization for coding and network, and offer combinations of synchronization methods as well as bidirectional synchronization.

12) Can operate independently of the management machine.

13) Automated data format conversion for wave recordingCOMTRADE 1999 Version orCOMTRADE 1991Version;

14) Advanced Anti-Interference Design: Utilizing8 LayerPCB、SMD Assembly and software fault-tolerance technology, interference resistance achievedGB/T14598 The stringent grade is set at Level IV standard.
