Intelligent dry load of generator set N Product Description: Ws-6400 series AC intelligent dry load can be typically applied to the generator test system. Based on the traditional load test equipment, it is optimized from the aspects of appearance design, process control, data recording, system integration and user experience, providing a fully automated generator load test. The system is composed of generator set auxiliary measurement and control instrument, generator set special measurement instrument, controller and load cabinet. It provides test items including various performance indexes of generator set and automatic load detection and test process, which is generated through data collection, data analysis and report. The test system is also applicable to the field test, performance demonstration, commissioning and acceptance of power generation units The load box is a purely resistive load, which is wound by a special alloy resistance, coated with stainless steel, with small temperature drift and long service life. The total power of a single machine is up to 50MW. The external chassis adopts a fixed container structure, with rain protection function, top air outlet, easier heat dissipation, automatic overheating protection function and automatic unloading function in case of fan failure. The load cabinet is equipped with a remote controller, Remote control can be realized. N function introduction: 1. It can measure the steady-state three-phase voltage, current, frequency, operation time and other basic functions of the generator. 2. It has the function of harmonic analysis, and can analyze the 2 ~ 50th harmonic content and total harmonic content of voltage and current at the same time; Electric energy accumulation function. 3. It has powerful voltage recording function, and is equipped with photoelectric isolation RS485 / RS232 serial port communication function, which has powerful serial port function. 4. It can not only measure all steady-state parameters, but also measure sudden addition, sudden discharge, voltage, current and frequency curves, voltage and current harmonic curves and harmonic content. 5. Load control function, which can complete the functions of sudden load addition and sudden load removal. 6. Optimize the segmented power input mode for convenient setting. 7. Loading and unloading can be controlled manually on the remote panel. N application fields: Load detection of generator set, high-power power supply and power station. | |
Product name | Intelligent generator test system |
Test function | 1. Steady state measurement: three-phase voltage, three-phase current, active power, reactive power, apparent power, power factor, frequency, electric energy operation time and voltage imbalance 2. Bａnd loading function: it can realize the automatic loading and unloading function from 0%, 25%, 50%, 75%, 99%, 110% and other power bands 3. Sudden loading and unloading test: it can capture the transient voltage, maximum frequency, minimum current and recovery time 4. Setting test: it can capture the maximum and minimum values of voltage and frequency setting, and calculate the relative rise and fall range and adjustment rate of voltage and frequency setting 5. Fluctuation test: it can capture the maximum and minimum value of voltage and frequency fluctuation, and calculate the steady-state frequency band, steady-state voltage deviation, voltage modulation, fluctuation rate and frequency 6. Harmonic analysis: 2-50th harmonic and its total harmonic; Record the real-time voltage waveform in 5 modes, with a recording time of 5 seconds to 5 minutes |
control mode | Mode1, touch screen, manual automatic control Mode2, computer software control (controlled by wenshin load intelligent test software) Mode3, RS485 communication (Modbus RTU communication protocol is provided to meet the automatic integration test) (the default is local touch screen control, and the user can select mde2 or Mode3) |
Loading mode | Steady state loading: preset a test value and test time, and conduct load test according to the set value Transient loading: preset a test value to complete sudden load and sudden load unloading tests Bａnd loading: preset multiple test values and test time, and automatically carry out load test according to the setting process |
Automatic power compensation | The system automatically tracks the on-line test power and realizes high-precision load test through program automatic compensation |
Automatic start and stop of fan | After the test, the fan keeps running and automatically shuts down after dispersing the internal preheating of the equipment. |
Automatic speed regulation of fan | The size of the fan test power value automatically adjusts the air volume to make the low-power test more silent |
Protection function | Overvoltage, fan fault, overtemperature protection, short circuit protection, phase sequence protection |
Data storage function | The system can record online test voltage, current, power and other parameters. The test data can be stored in Excel table and exported through USB flash disk for in-depth analysis. |
Extension interface | Modbus RTU, RS485, RS232, Ethernet port, can (default 485, optional according to requirements) |
