(6) Parallel machine: Each machine can be controlled by control devices under local control and remote control, and displayed real-time parameters of all the machines, by upgrading our existing equipment meet with our existing equipment simultaneously load and machine. Requirements are as follows:
1) Through the transformation of our existing multi-load equipment hardware or software, implementation and use of newly purchased equipment and machines, to add and subtract carrier synchronization, and the ability to display the load parameters.
2) Require manufacturers to inspect determined by the manufacturer shall not subcontract the work to complete the transformation.
3) The new equipment delivery within 60 days to complete the transformation of all existing equipment.
4) Connecting the old and new devices can communicate and meet the functional user requests.
(7) Control selection: Load control and remote control either-or, manual control and intelligent control either-or, avoid chaotic control.
(1) Communication: Intelligent control the use of opto-isolated RS485 communication port connecting the PC. You can also use the USB or RS232 communications port.
(2) Loading: Steady-state load (manual loading, pre-loaded, automatic loading); transient load (sudden unload).
(3) Manually load: input power and power factor, which is loaded by the specified value.
(4) Pre-loaded: Enter the generator set parameters, you can select 0%, 25%, 50%, 75%, 100-110% preset ratios, etc., automatically calculate the appropriate power for fast loading.
(5) Automatically load: You can set multiple stages of power load test time long, automatic test phase. The loading process can pause, or skip to the next stage.
(6) Step Load: In steady-state loading process, the load will gradually increase or decrease, a smooth transition to the target power, avoid unplanned sudden load unload, step interval values can be set free.
(7) Power Compensation: You can enter the resistance through software to compensate for line material, length and other causes of power loss.
(8) Parallel Machine Test: multiple load and machine can be tested, and the machine is running, you can display and record the parameters of each station loads, also display, record the total system after paralleling machine.
(9) Automatically: load and subtraction and addition and subtraction operations manual, can be set to load and run the program according to user needs.
(1) Real-time Monitor: Software display main parameter value, such as voltage, current, power, power factor, frequency and time.
(2) Data Collection Interval: the minimum steady-state data resolving time is 1 second, and the minimum transient data resolving time is 40μs.
(3) Stable Data Comparison: the max value and min value of all the parameters in steady-state test is listed in software interface, which is convenient for user to compare.
(4) Data Save and Query: All test data be saved in the software, according to generator set number, easy and fast check the history test data.
(5) Graphical Display: show real-time or history test data, and support to print curve and graph as follows:
1) Voltage, current, frequency and power curves in real-time; 2) voltage curve;
3) Current curve; 4) power curve; 5) frequency curve; 6) power factor curve;
7) Instant load voltage curve; 8) instant load current curve;
