Problems solved by technology
At this time, the switching speed of the compensation capacitor is relatively slow, usually at the second level, which cannot meet the requirements of some application scenarios that require fast reactive power compensation (such as the flying shear process in the steel industry, the spot welding machine operation in the automotive industry, and other actual operating scenarios). Compensation requirements, resulting in a relatively low speed of reactive power compensation

The invention provides a control method, device and equipment for rapid reactive compensation and a storage medium, and the method specifically comprises the steps: collecting a three-phase electric signal sequence from a target power utilization system, selecting one phase of electric signal sequence as a target electric signal sequence, and enabling an analog-to-digital conversion result of the target electric signal sequence to serve as basic control data; when reactive compensation is carried out, calculating a first power factor of the current half detection period by using the basic control data in the current half detection period; acquiring a second power factor of the first half detection period, and taking a sum value of the first power factor and the second power factor as an actual power factor of the complete detection period; and the switching state of the compensation device is controlled by judging whether the actual power factor is within the standard power factor interval of the target power utilization system or not. Thus, through a half-wave detection mode, the response time of the compensation device can be shortened, and control errors caused by asymmetry of upper and lower waves of a system waveform and median line offset are avoided.
Description
technical field [0001] The present application relates to the technical field of reactive power compensation, in particular, to a control method, device, equipment and storage medium for fast reactive power compensation. Background technique [0002] Reactive power compensation, also known as reactive power compensation, is a technology that improves the power factor of the power grid in the power supply system, reduces the loss of power supply transformers and transmission lines, improves power supply efficiency, and improves the power supply environment. It can be seen from this that the reactive power compensation device is in an indispensable and very important position in the power supply system. Reasonable control of the compensation device can minimize the loss of the power grid and improve the power supply efficiency and quality of the power grid. [0003] At present, in the passive compensation scheme, the contactor switch is often used to control the switching stat...
