Design And Implementation Of Intelligent Capacitor System

With the continuous advancement of domestic modernization level,more and more high-power devices and non-linear load equipment are widely used.The use of a large number of non-linear load equipment and high-power electronic equipment has also affected the power quality of the three-phase power grid to a certain extent.The complex power quality will inevitably affect the power equipment.In turn,the power equipment will further affect the power quality of the power grid,which will cause a vicious circle between the power grid and the power equipment.Therefore,it is of great practical significance to develop a high-performance smart capacitor to improve the power quality of the power grid.Based on the power company’s related functional requirements for smart capacitors,the system performance indicators of the entire system were first clarified,and according to the system’s related functional requirements,a block diagram of the entire system structure of the smart capacitor was established.At the same time,the related working principles and algorithms involved in the smart capacitors designed in this article are discussed in depth.Based on the structure diagram of the intelligent capacitor designed above,the entire system hardware circuit is built.The system takes the microprocessor as the core,and realizes various functions of the whole system by means of corresponding peripheral function modules.After completing the system hardware circuit design,design the system software program according to the functional requirements.When designing the system software program,the software structure of the intelligent capacitor system software program is first built.Taking into account the difficulty of system software program development and subsequent software program upgrade and maintenance,this article uses a modular idea to design.In consideration of the real-time nature of the software program,the multi-tasking design idea is fully incorporated in the design of the functional module software program in this article to avoid the microprocessor being occupied by a certain functional sub-module program for a long time,which effectively improves the overall real-time of the system software program Sex.In order to verify the overall performance of the smart capacitor designed in this paper,a complete system of smart capacitors is built according to the designed hardware circuit and software program.Functional tests are performed on the system’s hardware circuits and software programs on the built intelligent capacitors.After completing the system function test,test the overall performance index of the system and record the relevant test results in detail.According to the analysis of the relevant test results,it can be known that the functions and performance indicators of the smart capacitor designed in this article meet the relevant index parameters set at the beginning of the design,and have high market application value.
