What Are The Contents Of The 1MW Load Bank Rental Test? What Are The Control Methods?

What are the test contents of the 1MW load bank?
(1) Steady-state test: It can load any power within the rated value, measure and display the generator set steady-state three-phase voltage, current, active power, reactive power, apparent power, power factor, frequency, running time and other parameters.
(2) One-button loading and unloading: whether manual switch or software control is used, the power value can be set first, and then the total loading switch is activated, and the load will be loaded according to the preset value, so as to avoid the load caused by the power adjustment process. fluctuation.
(3) Setting test: After 100s setting time, the maximum and minimum values of voltage and frequency setting can be captured, and the relative voltage and frequency setting rising and falling ranges and adjustment rates can be calculated.
(4) Fluctuation test: Through the 60s fluctuation time, the maximum and minimum voltage and frequency fluctuations can be captured, and the steady-state frequency band, steady-state voltage deviation, voltage modulation, fluctuation rate, and frequency can be calculated.
(5) Sudden addition test: The sampling interval is 40μs, which can capture the transient voltage, current, maximum and minimum value and recovery time of the transient voltage, current, frequency and recovery time when the load suddenly changes, and calculate the sudden transient voltage deviation and transient frequency difference.
(6) Sudden unloading test: The sampling interval is 40μs, which can capture the transient voltage, current, frequency maximum, minimum and recovery time when the load suddenly changes, and calculate the sudden reduction transient voltage deviation and transient frequency difference.
(7) Harmonic analysis: It can analyze the 2~50th harmonic content and total harmonic content of voltage and current at the same time.
(8) Wave recording analysis: 5 modes to record voltage real-time waveform, recording time 4～280s. Accurate sampling of up
to 128 points per cycle is possible.

What are the control methods of the 1MW load bank?

(1) Local manual control or remote automatic control of the load can be selected.
(2) Local control: The load is equipped with a local control panel, and is divided into several power gears, which can be controlled by switches.
(3) Remote control: Control the load through the data management software on the computer, realize all test functions, display, record and manage the test data, generate various curves, charts, test reports, and support printing.
(4) Control mode interlocking: The system is equipped with a control mode selection switch. After selecting any control mode, the operations performed by the other modes are invalid to avoid conflicts caused by multiple operations.
(5) Local instrument display data: 1MW load bank can display three-phase voltage, current, active power, reactive power, apparent power, power factor, frequency and other parameters through the local measuring instrument, and the data of 2 independent load loops can be It can be displayed alone, and the total data after parallel machines can also be displayed.
