The invention provides a voltage compensation system. The system comprises a power supply device which provides power for a PLC device, and a voltage compensation device which is connected in parallelwith the output end of the power supply device. The voltage compensation device is used to detect the output voltage waveform of the power supply device in real time, and perform voltage compensationwhen abnormality is detected in the output voltage waveform. According to the voltage compensation system provided by the invention, the voltage compensation device is connected in parallel with theoutput end of the power supply device to achieve unified compensation at the voltage source, thereby greatly reducing installation and maintenance costs; in addition, the voltage compensation device provided by the invention works only when the output voltage of the power supply device is abnormal, such as frequency missing; the energy consumption is extremely low, which is conducive to environmental protection and energy saving; and furthermore, compared with a UPS power supply, the voltage compensation device has the advantages of small size, low energy consumption, low heat, convenient installation, low maintenance cost and the like.
Description
technical field [0001] The present invention relates to the field of electric power, in particular to a voltage compensation system, method, computer-readable storage medium, and terminal. Background technique [0002] In order to prevent program interruption and data loss caused by sudden power failure or voltage flicker in the computer power supply system, UPS power supply is often used to solve the above problems. [0003] However, under normal circumstances, the industrial computer PLC used in industrial production equipment does not have the conditions to install a UPS power supply, which is expensive and difficult to install. Therefore, when the power supply voltage of industrial computer PLC drops, it will cause PLC program interruption and equipment shutdown, which will cause a large degree of production stoppage and raw material loss, and damage the efficiency of enterprises and social economy. [0004] Therefore, users urgently need a power compensation scheme tha...
