Substation Voltage And Reactive Power Control Based On DSP

Voltage is a measure of power quality is an important indicator, related to the power grid safe and stable operation, therefore, ensure the voltage quality of power system security compliance is an important condition for high-quality power supply. Reactive power compensation is guaranteed to run an important means of high-quality, power system is a major topic of research. China and the world's developed countries, the quality and supply stability in the power supply there is still a large gap between the substation and reactive power control mode, therefore the research is a real issue of concern.This paper analyzes the reactive power balance and the relationship between the voltage level, recognizing the power system voltage regulation complexity, and then discuss the principle of voltage and reactive power control, in the analysis of projects focused on the use of more traditional nine-area control strategy flawed Based on the proposed new control method, the picture shows the basic method to nine areas, in easily lead to frequent moves on the border prior to the adoption of BP artificial neural network intelligence, adjustment of transformer taps and capacitor switching, make full use of the BP network prediction the reduction in the border region in the nine zones blindness on the action and thus greatly reduce the on-load tap tap adjustment.System hardware design, the system uses the control chip is TI's production of TMS320LF2407, the system main modules include: signal input module, main control module, communication module, display module, the state instructed the module and keyboard module, described in detail in the various module design and operating principle, the system has an automatic sample calculation, reactive automatic adjustment, it is important to set parameters in real time, fault alarm, data communication and other functions.System software design, this article using the C programming language, using TI's Code Composer Studio provides an integrated debugging environment to debug compiled under. This follows a modular programming ideas, the entire software according to the tasks to be completed, divided into four modules: data acquisition module, liquid crystal display module, keyboard control module and serial communication modules. Described in detail the various tasks of the division of the task modules, procedures, processes and key functions.This article is designed intelligent reactive power regulator has passed the preliminary MATLAB simulation, the results show that the controller hardware and software design is reasonably practicable, the performance is stable and reliable, to achieve the desired functional requirements.
