The Hydroturbine Speed Control System Simulation Tester

1.Software System

The hydroturbine speed control system simulation tester features a powerful software system that not only ensures the instrument can conveniently perform various tests but also significantly enhances its flexibility and versatility. The main features of the instrument's software system can be summarized as follows:

1. The instrument can automatically generate test reports in Word and Excel formats.

2. The test reports automatically label curves, making the report generation process fully automated.

3. The names and units of all sampling channels can be redefined.

4. Test environment settings and instrument configurations for various tests are automatically saved.

5. Five built-in turbine models-mixed-flow, axial-flow, impulse, through-flow, and nonlinear-support simulation for different types of governors.

6. Test parameters for various tests are automatically calculated.

7. Simple and convenient channel filtering methods.

2. Hardware Sys

The hardware system characteristics and technical specifications of the hydroturbine speed control system simulation tester are as follows:

1. 8-channel low-voltage/current analog acquisition; voltage and current can be freely converted; voltage input range: -10 V to 10 V; current input range: -20 mA to 20 mA; sampling error is less than 0.2% across the full scale range of 10% to 100%

2. 2 frequency measurement channels, with a range of 45 Hz to 55 Hz, a frequency resolution of 0.001 Hz, a measurement error of less than 0.001 Hz, and a frequency measurement voltage input range of 0.5 V to 110 V

3. 2 passive node digital measurement channels

4. 2 active node digital measurement channels, with a digital signal input voltage range of 12 V to 220 V

8. Test data can be easily exported using storage devices such as USB flash drives or portable hard drives.

9. Real-time plotting of test curves, along with a variety of curve analysis tools, allowing users to freely zoom and position curves

10. Windows XPE operating system enables self-protection and recovery of the software system, preventing virus intrusion and damage

11. Anti-jitter processing is employed to prevent user errors

12. Real-time monitoring of input signals; input signals exceeding the measurement range are automatically cut off in a timely manner to protect signal acquisition channels and the instrument

5. 8 analog acquisition channels using isolated acquisition, with mutual isolation between channels

6. 2 active-terminal digital measurement channels, with a switch signal input voltage range of 12 V to 220 V

7. 1 4–20 mA analog output channel, with an output error of 0.2%

8. 1 frequency output channel with a resolution of 0.001 Hz; output error of 0.001 Hz within the 45 Hz–55 Hz range; output voltage amplitude: 12 V AC

9. Touchscreen interface for human-machine interaction

10. Built-in 32 GB data storage

11. 12.1-inch color display
