This paper is concerned with the power quality and efficiency the power system. The system is being complex day by day so there is a need of an automated system to control and supervise the substation. In projected work the substation is modelled with a microcontroller and a GSM module that improves the quality of power transfer and reduces the no. of outages. A platform is used to display the various calculated parameters like voltage, frequency, current, phase angle. All these parameters are sent by a SMS as the system comprises of a GSM module which is interfaced with a microcontroller. The sensors placed at the substation senses the situation and then send related signals to the connected microcontroller. All the mentioned parameters are equated to their pre-defined values in a continuous way to provide protection. Under faulty conditions the unit gets shut down by the employed relays. An alert message can be sent in this situation for indication. Thus, the work is increasing the efficiency of substation in an intelligent manner.

The Development Trend

With the development of national economy, the progress of science and technology and the height of the production process automation, various nonlinear loads in power grid grow rapidly together with a variety of complex, precise and sensitive power equipment. The above-mentioned two aspects of contradiction is more and more prominent and the requirement of users for power quality is also higher. In such situation, this paper discusses the related theory and its control technology in the field of power quality, analysis the development trend of power quality management and control in our country, which has a strong practical significance. This paper expounds the main problems affecting the quality of electric energy, and analyze in detail the way to improve the quality of electric energy, and then give a preliminary discussion on the development direction of this field.

Abstract This paper considers an approach that demonstrates the features of creating complex electrodynamic systems. In practice, the creation of such objects is associated with a decrease in the levels of electromagnetic radiation, control of the direction of propagation of electromagnetic waves. The main properties of the generated automated system for assessing the quality of the electrodynamic characteristics of objects are considered. Suggestions are given on its structural diagram, the contours of the operation control and control of the restructuring of electrodynamic objects are shown. The created system for assessing the quality of electrodynamic characteristics can be useful in the design of a wide class of technical systems.
