1. Introduction
The performance index of series LBD-MGR is satisfied in operation since commissioning in 1996. It has passed the quality inspection of the Electric Power Administration of P. R. in China, bridging a gap successfully at home. We have been working on the production to upgrade it for many years. With the acceleration of the demand in power system and the improvement of relay protection technology, we realize that dynamic record is the best way to monitor, record and analyze the running state in power system for it can’t meet the requirement to record simply.
LBD-MGR-8000 is based on the hardware of original recorder. They are new generation of embedded dynamic recorder with independent intellectual property. They meet the professional standard of DL/T553-94, DL/T663-1999 and DL/T873-2004 totally. We adopt high performance, low consumption embedded hardware as platform configured with embedded real-time operating system. They are mainly applied for recording voltage, current and relay protection device’s action sequence under different fault states in power system, to help operators analyzing the failure cause correctly. LBD-MGR-8000 is mainly applied in thermo-power plants, hydroelectric power plant and nuclear power plant.
2. Technical Characteristics
2.1 High Performance Design with Embedded Hardware Platform
It can accomplish calculations of kinds of initiate mode in a short time to judge the fault rapidly and accurately for the sample and calculations are performed by 32-bit floating DSP that is low consumptive and powerful in calculation. EXT embedded main board without fan is in charge of data processing. The main board is low consumptive, stabile, reliable and tailored arbitrarily according to actual demand to design kinds of I/O mode. The stability and reliability are improved greatly because of the application of large scale of programmable logic device, craft of SMD and 6 layers PCB.
2.2 Stabile and Efficient Design with Embedded Software Platform
We adopt multitask real-time embedded operating system used by international military. The system has many efficient characteristics, such as simplify the program, tailor the program according to actual demand, run in junior embedded system and occupy less computer resource. The use of embedded system avoids computer virus and despiteful attack on the net, it ensures that user′ mistake or virus would not damage or paralyze the system.
2.3 High-speed Data Acquisition
The maximum sampling frequency is up to 20 kHz and the resolution of digital event channels is 0.05ms. It provides high quality data source for analyzing fault, distance-measurement, monitoring operating state in detail; It is helpful discover the limitation of the new device and the hidden problems of the device operating for years for operators; It is useful to reoccur fidelity fault wave, reflect the quality of power support truly, discover the abnormality of operating device.
2.4 Humanity Visual Self-diagnostic Warning Function
The self-check on main surface mount chip is necessary because of redundant design of hardware. The error display visually if chip is damaged, avoiding the defect that the serviceman can not maintain when the network interrupt or the back computer fail; It also can be reported by remote dispatching or transmitted to analyze station.
2.5 Independent Operation in Safe Mode
The set adopts 6U cabinet design and has perfect ability to protect the set from disturbance. It is convenience to install, maintain and debug. Create running and operating log automatically and record the operation status in detail for reference. To output and display wave analysis, the set configures with large screen TFT liquid crystal display.
2.6 Transient, Steady-state Data Adopt Independent Double Channel Storage, Transmission Technology
Transient data and steady-state data store and transmit independently. It has steady-state record function to record data in normal system, including electric parameters, such as voltage, current, active power, reactive power, frequency etc. The set begins to record consecutively when it starts normally, it goes on when something abnormal happen to the system or it records transient data because of fault start. It ensures that the data in the whole procedure of per disturbance can be recorded completely when long-time disturbance (pollution of system for example) happen to the power network consecutively for many times.
2.7 Security Storage of Large Volume Data
The set adopts advanced hardware design to save record data directly to disk. For large capacity of storage medium have the ability to record consecutively, the volume of memory has no effect on the volume of the record data. Backup data dually ensure the security against the influence of network and power down.
2.8 Network Function
Support TCP/IP communicate protocol; Support IEC 870-5-103 communicate protocol; Support Ethernet; Support multiple communicate modes such as double cord, coaxial cable, optic fiber, phone line. It is convenience to communicate and combine network with other management system.
2.9 Electrical Test Function
Exciter no-load test: Generator short test; Generator no-load test; Main exciter load test while generator no-load ; Main exciter load test when generator short; Generator no-load excitation-loss test; Excitation system step response test; Generator zero-initial voltage boosting test; Main transformer zero-initial voltage boosting test; Network incorporated synchronically test; self-defined test etc.
3. Technical Parameters
3.1 Maximum Sampling Frequency: 20kHz；
Modular Transforming Precision: 16 bits;
Resolution of Digital Event Channels: 0.05ms； The Highest Harmonic Resolution Ratio: 99 times.
3.2 Data Recording Mode
The mode is classified into stable record and transient record, the data is marked with absolute time.
3.2.1 Steady Record
It records electric parameters consecutively, such as voltage, current, active power, reactive power, frequency etc. The interval of the data can be set as 0.02s or 1s.
