Electric energy, as an important material basis for the survival and development of human society, is closely related to the national economy and people's livelihood and strategic competition. Throughout China's power system, if we want to fundamentally guarantee the sustained growth of social economy, we need to ensure the quality and safety of power supply in the whole system. In recent years, with the continuous enrichment of the types and form of electrical products, the demand for power resources in social production and life expanded gradually, to a certain extent, it stimulated the application of all kinds of electrical appliances in electronic technology. Especially, the electrical engineering and its automation technology are widely used in the construction of various projects. Through their own standardization and refinement, the electric power system has greatly promoted the progress and development of the power system in the aspects of operation reliability and stability.[1] This paper focuses on the electrical engineering and its automation technology, and analyzes the advantages of its application in the power system, and looks forward to the future development trend of the technology in the power system from the perspective of long-term interests.

One of the most complex disciplines in electrical engineering is power system protection which requires not only the proper understanding of the different components of a power system and their behaviours but also a good knowledge and analysis of the abnormal circumstances and failures that can occur in any element of a power system. Moreover, the rapid changing and development in relays principles as well as in their technologies are additional factors that oblige those people working in the field to expand and update continuously their knowledge. In this paper, we shed light in the evolution of protective relays since the onset of electrical energy to currently. We try also to foresee the future prospects and trends in this area.

In this paper we introduce the computer software fault analysis system to the power fault detection system, and design power fault elimination system of electrical engineering automatic control, and do simulation and experimental study on the performance. When using the turbine blade of electric machinery to detect fault, we can get the automated troubleshooting displacement curve, and using computer simulation to get the electric mechanical stress distribution nephogram. To further verify the effectiveness of the algorithm, we test the frequencies for eight different units, and obtain eight different sets of five order fault diagnosis frequency, and draw the frequency spectrum distribution of frequency response. It provides the theory reference for the automation of power system fault exclusion.

The Stability

The low-frequency oscillation is one of the most important reasons that affects the stability of the power system. Under the background of building a unified and strong smart grid, the scale of the power system will continue to expand, the interconnection of systems will be more closely, the structure will be more complex, these factors will further increase the difficulty on the low-frequency oscillation control. This paper summarizes the methods to analysis low frequency oscillation signal, the way that suppresses the low frequency oscillation in electrical engineering. Further, based on smart grid framework, a on-line visualization technology and a self-recovery regulation strategy are proposed to damp low-frequency oscillation.

The present study was carried out to study the emotional intelligence of Electrical Engineering students in Dire Dawa University Ethiopia. The sample for the study was 90 (30 Industrial control engineering streams, 30 Power system engineering streams, and 30 Communication engineering streams) randomly selected from Dire Dawa university, school of electrical and computer engineering. A sample scale was employed for the data collection and a t-test was employed for the analysis of data. The outcome of the study shows that Industrial control engineering and Power system engineering students do not differ significantly on various dimensions of Emotional intelligence and Industrial control engineering and Communication engineering students do not differ significantly on various dimensions of Emotional intelligence and Power system engineering and Communication engineering students differ significantly on various dimensions of Emotional intelligence.

In view of the teaching requirements of the new curriculums about new energy power generation technology in electrical engineering field, this paper has proposed and designed a rated 3kW wind power system under the environment of PSIM9.0 software. Through systematically analyzing the mathematics and theory knowledge of the small and medium sized permanent-magnet direct-drive wind power system (PDWPS for short), the wind power system model has been built and the back-to-back double-PWM control circuit has been designed. Then the whole PDWPS has been established based on PSIM. The simulation results show that, when the wind speed changes, the output power of the generator is stable and the DC voltage of the inverter is constant. The results prove that the control strategy is correct and valid. As a powerful auxiliary teaching tool, PSIM can be used to strengthen student's understanding of theoretical knowledge and improve the students' learning interest and enthusiasm. The contents in this paper provide a new method to the teaching and practice in electrical engineering courses.
