Description

Technical Field

[0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a hybrid reactive power compensation device and a use method thereof. Background Art

[0002] Reactive power compensator is a compensation device. Its role in the electronic power supply system is to improve the power factor of the power grid, reduce the loss of power supply transformers and transmission lines, improve power supply efficiency, and improve the power supply environment. Therefore, reactive power compensation devices are in an indispensable and very important position in the power supply system. Reasonable selection of compensation devices can minimize network losses and improve the quality of the power grid. On the contrary, improper selection or use may cause many factors such as power supply system, voltage fluctuations, and increased harmonics.

[0003] Traditional reactive power compensation systems usually adopt a dual-cabinet design, with each cabinet equipped with a set of mutual inductors to monitor the reactive power demand in the circuit, and each cabinet is equipped with a controller to independently analyze the power quality of each circuit. Although this configuration has achieved the zoning management of reactive power compensation to a certain extent, it often faces a significant challenge: the difficulty in regulating the compensation accuracy. Since the two controllers act independently and make judgments based only on local information, it may lead to the occurrence of "over-compensation", that is, excessive compensation, which in turn affects the overall efficiency of the power grid; and when trying to avoid over-compensation by reducing a set of compensation devices, it may cause the problem of "under-compensation", that is, insufficient compensation, and unable to meet the power grid's demand for reactive power. This frequently switching compensation strategy not only affects the stability and economy of the power grid, but also leads to frequent operation of the controller and components that perform compensation (such as contactors, capacitor banks, etc.), aggravating the mechanical wear and electrical stress of the equipment, thereby greatly shortening the service life of the equipment.

10. A hybrid reactive power compensation device and a method of use, applicable to a hybrid reactive power compensation device according to claims 1 to 9, characterized in that: The following steps are involved: Step 1: Install the device: first install the display mechanism (4) on the control mechanism (3) through the positioning tube (33), then install the connecting plate (2) and the control mechanism (3) together through the connecting screw (9), and then install the fixing plate (1) and the connecting plate (2) together through the installing screw (6), so that the installation and fixation of the entire device can be achieved; Step 2, reactive power compensation: by combining the SVG module with the SVC module through the YD-DWB component (35), the performance advantage of the SVG module can be increased on the basis of the SVC module, thereby improving the cost performance of the entire reactive power compensation system. The reactive power generated by the load is compensated by the SVC module first, and the dynamic process and the compensation difference of the SVC module are supported by the SVG module, thereby ensuring the dynamic characteristics and compensation effect of the reactive power compensation of the system; Step 3, information display: by embedding a control unit inside the monitoring module (44), the monitoring module (44) has rich functions such as real-time data acquisition, storage, real-time control, and USB, and the monitoring module (44) provides a rich human-computer interaction interface and also provides the user with a voltage and current waveform display function, and then uses the color touch screen (42) as a monitoring and setting center, and the user can view the current voltage, current and power factor information through the color touch screen (42); Step 4: Heat dissipation of the device: ventilation and heat dissipation inside the device can be achieved through the heat dissipation fan (56) and multiple heat dissipation pipes (57). Then, through the refrigeration box (58) and the circulating refrigeration pipe (59), one end of the circulating refrigeration pipe (59) draws out the refrigerant in the refrigeration box (58) and returns the refrigerant through the other end, so as to achieve water cooling of the device, thereby enhancing the heat dissipation effect of the device and extending the service life of the device.
