Design Of Shen Yang Dong Chang 66kV Substation And Intelligence Reform

To promote Shen Bei Urawa Shenyang Metro development to meet the needs of the region’s new power load, the proposed Shenyang East Course substation to improve power supply reliability and quality of power supply in the region.This paper Shen Bei load material selected from the calculation of load forecasting, flow calculation, short-circuit current calculation, the main electrical equipment, layout, communications and other considerations, to the raw data as the basis, and in accordance with the relevant provisions of the statute to the economic operation of the substation target site design, content and design including the following achievements:(1) In view of the major projects in Shenyang Agricultural YURUN global procurement center opening in Metro original power lines long, low reliability issues outstanding, the proposed unattended, the whole family, occupies a small East Course 66 KV substation, to provide the relevant basis for construction-related substations.(2) Once the electrical, secondary electrical, protection, SCADA, remote communications and information systems to do a detailed demonstration of the associated electrical equipment for a rigorous configuration. On this basis, describes the energy-saving measures related impairment transmission, substation, construction, the proposed method of how to solve the problem of environmental pollution in the technical aspects, economic aspects and environmental levels to verify the feasibility of the scheme.(3) On the basis of 66 KV substation design was carried out on intelligence reform, including intelligence reform and transformation of the overall structure of a substation substation equipment. After transformation, intelligent substation structure is more compact, clear, hierarchical, can achieve a real-time data acquisition equipment and on-line monitoring and other functions, and the information can be shared between devices, enables more complex algorithms relay function. Intelligent substation intelligent transformation of the region to develop grid foundation.Anyway, after a rigorous design, substation safe, economical, environmentally friendly operation, repair and maintenance to reduce the frequency and intensity of labor, but also convenient and easy future expansion or secondary wiring capacity increase.
