RC2000 Harmonic type reactive power automatic compensation controllerDetailed product description：

The RC2000 harmonic type reactive power automatic compensation controller is widely used in various compensation equipment, with a high-performance 16 bit microprocessor as the core and Fourier series algorithm to obtain all fundamental power data. It is particularly suitable for compensation control in harmonic sources or filtering and harmonic elimination compensation devices.

At present, the pollution of the State Grid is quite serious, with harmonics present in most situations, which has raised higher requirements for power supply equipment. It is necessary to compensate for reactive power and eliminate harmful harmonics through filtering and harmonic elimination. But the requirements for the components selected in such filtering and harmonic elimination devices are relatively high, especially as compensation control components, the requirements are even higher. Otherwise, the effect of the harmonic elimination filtering device cannot be fully utilized or even achieve the filtering and harmonic elimination function. Some general reactive power compensation devices may encounter situations such as the following during operation, and the anti harmonic capability of the compensator should be considered. 1. The power factor cannot meet the predetermined target. 2. The switching is too frequent. 3. Similar situations occur when replacing the controller.

1. The RC2000 harmonic type reactive power automatic compensation controller adopts a composite real-time harmonic filtering control method. Through real-time measurement by the controller, a comprehensive detection of power grid harmonics is first carried out. Then, the controller analyzes the content of each harmonic and controls the capacitors of the filtering circuit for reactive power compensation and harmonic filtering based on specific harmonic characteristics. Ultimately achieving the filtering goal of overall harmonics. And it can correctly display the power factor in the presence of harmonics and operate reliably.
2. It has harmonic over limit protection function, overvoltage and undervoltage protection function, which improves the service life of the capacitor cabinet. Note: If the components configured in the compensation device can withstand the range, the harmonic protection parameter can be increased to enable the equipment to work normally.
3. It has two working modes: automatic operation and manual operation, making it easy to install and debug.
4. Alarm function: When there are harmonics exceeding the standard, overcompensation, overcompensation, high voltage, low voltage, the passive switch is closed, and the user can connect the alarm to sound an alarm.
5. Equipped with a capacitor discharge time setting, it ensures that each group of capacitors has sufficient time to discharge when repeatedly activated, thereby improving the service life of the contactors and capacitors on the capacitor cabinet.
6. High measurement accuracy of power factor and other grid parameters, with ultra wide range LED display.
7. There are 12 encoding output methods for users to choose from. By combining capacitors of different capacities, different output capacities can be obtained, achieving stepless compensation effect and keeping the target power factor in the optimal state. Optimize switching to reduce the number of switching times, improve compensation accuracy, and prolong the service life of capacitor cabinet components.
8. The human-machine interface is user-friendly and easy to operate, and data is not lost in case of power failure.
9. One click operation. The operation process is very simple and does not require complex parameter settings.
10. Can be ordered as both contact type and non-contact type (dynamic compensation controller), please specify when placing an order. The dynamic compensation controller can dynamically track changes in reactive power in the power grid and quickly compensate, with a response speed of less than 20ms and an output capacity of 20Ma DC12V per branch. Eliminate voltage fluctuations and suppress voltage flicker
11. Real time display of power grid parameters: harmonic total distortion rate, fundamental power factor, total power factor, voltage value, current value, 2-25th current distortion rate, 2-25th voltage distortion rate, reactive power, active power, apparent power, grid frequency, and other parameters.
12. Installation dimensions include: 138 * 138, 162 * 102, 113 * 113, etc.
13. Can achieve communication function.
