The Design Of San Jiazi 66kV Smart Substation On Liaoning Tieling

With the development and the national economy in terms of power consumption level rise, the traditional network can not meet to the power demand, on this basis in order to meet the needs of development and power to load their own development, the construction of smart grid strong will be incorporated into the national strategy. For the status of the smart grid in the development of China’s power grid construction in the increasingly apparent, which will greatly promote the development process of China power grid.In order to meet the load development in the Tieling San Jiazi areas of need and the reliability of power supply demand, through the design of the power system substation knowledge learned in Tieling San Jiazi 66 k V voltage level of electrical design.First of all, through the analysis of Tieling San Jiazi regional economic development situation and the demand of economic development situation in the area under the load status and the development of local power supply reliability, feasibility of construction of intelligent substation three sub areas of the analyses. And then compared to determine the wiring of the master station of electrical wiring of intelligent substation San Jiazi of 66 k V voltage class through the analysis of several typical of the main electrical wiring, at the same time, according to the nature of the local load composition and size and load the future development of the situation in reference to the user’s requirements on power supply reliability based on the number and type of station the main transformer. Through the calculation of short-circuit current of the main electrical equipment selection and station; lightning protection of substation grounding, AC and DC electric station and substation two system design.
