Product features:
           
The BWRBWST stepper turbine governor replaces the traditional electro-hydraulic converter with a stepper motor driver and a stepper motor, eliminating the swivel motor speed mechanism and buffer for easy access and maintenance. Due to the use of software frequency measurement, it overcomes many defects of the hardware frequency measurement circuit and makes full use of the advantages of programmable high reliability. Therefore, the stability is good, and the operation is very clear due to the use of the Chinese touch screen display, the running state, the parameter setting, etc. Convenience.
 
The state monitoring of the turbine governor is mainly to realize the real-time monitoring of the state of the governor through the computer, and to master the operating state of the equipment, mainly including various detection, measurement, monitoring, analysis, and discriminating methods, combined with the history and current status of the system, and comprehensive consideration of environmental factors. Evaluate the running status of the equipment, determine whether it is in a normal state, display and record the status, and make an alarm to the abnormal status so that the operating personnel can process it in time to provide basic data for equipment failure analysis, performance evaluation, rational use and safe work. . The typical turbine system speed control system condition monitoring system mainly includes four major components: 1 sensing and transmitter; 2 governor control cabinet; 3 industrial computer and man-machine interface; 4 background integrated diagnostic monitoring system Distributed structure, various sensors are installed on the monitored equipment, the governor control cabinet is responsible for data acquisition, and performs general data processing, conversion and alarm, and communicates with the industrial computer through communication. The industrial computer is responsible for complex data processing and storage. Based on the unified information platform, it realizes the collection of state data of the turbine unit adjustment system, feature calculation, real-time monitoring, fault recording, performance test data record, and comprehensive online diagnosis and status of the background unit. The maintenance assistance decision system provides a reliable source of data.
 
1. measure the frequency of the unit and the power grid, and realize the frequency regulation of the unit when it is running without load or in isolation;
 
2. when no load is on, the unit frequency automatically tracks the power grid frequency, which is convenient for rapid automatic synchronization;
 
3. manually start and stop, increase and decrease load, and operate with load;
 
4. automatically start and stop the machine, and automatically adjust unit output according to permanent slip (bp) after grid connection;
 
5. switch automatically and manually unconditionally and without disturbance;
 
6. main parameters and operation status of speed regulators such as machine frequency, network frequency, guide blade opening, manual and automatic are displayed on the display screen;
 
7. able to set the operating parameters of the governor through the display screen;
 
8. when an electrical fault is detected, it can be automatically cut to manual and the load can be fixed in the state before the fault.
 
9. high reliability programmable controller (PLC), small size, strong anti-interference ability, and an average trouble-free time of more than 300,000 hours;
 
10. software frequency measurement can meet the requirements of timing and accuracy of frequency measurement;
 
11. PID intelligent control, with good stability and adjustment quality
