Improving the efficiency of power supply systems through the combined effect of voltage distortion
In most cases, any abnormal mode in the distribution electrical network is eliminated by the action of relay protection and automation devices (RPA), i.e. - there is a shutdown of the damaged item. It is much more difficult to constantly maintain the normal key indicators of the quality of electrica...

description |
In most cases, any abnormal mode in the distribution electrical network is eliminated by the action of relay protection and automation devices (RPA), i.e. - there is a shutdown of the damaged item. It is much more difficult to constantly maintain the normal key indicators of the quality of electrical energy in the network. With the advent of controlled voltage converters based on transistors IGCT and IGBT, static synchronous compensators STATCOM were developed. The main disadvantage of this kind of device is that the control output generated by them is static. Under conditions of increased likelihood of abnormal conditions, their dynamic compensation will be much more effective. In the process of research, the methods of dynamic continuous action of voltage on a sinusoid in a distribution electric network were used. The development of a theoretical approach was accompanied by constant monitoring of existing and developed technical solutions associated with the task set in the work. The object of the study was the distribution electrical network of industrial enterprises with a sharply alternating nature of negative network perturbations. A method has been developed for dynamic suppression of amplitude-phase voltage distortions on the basis of restoring the voltage curve due to the continuous introduction of a compensation voltage curve into the network via a booster transformer. A faster formation of the control action in comparison with analogues allows us to more effectively respond to negative network perturbations in distribution networks, especially if the nature of their occurrence changes dramatically. The proposed method is designed to maintain the quality of electricity within acceptable limits in accordance with the requirements of Russian State Standard 32144-2013. |
