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.

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.

Fault analysis is an important aspect in the successful operation of a power utility grid. The occurrence of faults in the system is not avoidable as causes of faults are not particularly one but of many with different causes and nature. It is one of the most important as well as it one of the most complex tasks in power engineering. The studies and discovery of faults in electric power systems is essential in ensuring the consistency and the stability if the power grid. Another importance of carrying out fault analysis gives a fair idea of the voltages and the current magnitudes under faulty conditions for different scenarios. This is helpful in the design of protection devices such as fuses, circuit breaker ratings, over current protection relays and other devices that are used for the protection of the system. Protection devices are important features of the power system grid mainly because their role in saving equipment and also human lives. In this paper, we investigate and analyze the behavior of electric power systems under fault conditions and then evaluate various practical scenarios.

We consider the information sharing, distributed processing and interoperating caused by different Standards and information models in this paper. For various parts of Power Grid such as generation, transmission, transformation and etc. A division method based on automatic control theory is proposed. With the large quantity collection of electric power production, operation and control information, we classify the information to the 4 categories and 12 sub-categories. The Quality Function Deployment (QFD) method is introduced as an innovative usage for evaluating the classification results, which is widely used in the procedure area of production. The division method for the information of power system is proved to be novel and the classification results can be used as the fundamental research of united power information model for further Smart Grid.

Power system transients, which are always present in a system due to switching in the presence of inductance and capacitance, are unwanted things. They are an ignored topic in the electrical engineering curriculum of many institutes. This paper presents our new attempt to teach electric power system transients for graduate students of the Electric Power System Management Energy Program at the Asian Institute of Technology (AIT), Thailand.
