Abstract
35kV substation integrated automation system for unattended form, the design shall be subject to the power grid dispatching automation design, its configuration, features include the arrangement of equipment shall meet the power grid security, high-quality, layered economic operation and information transfer, the total resources the principle of entitlement. Therefore, this design we will use this as the guiding principles of design to start design work. The entire design process including the step-down substation electrical design, microprocessor-based protection and the integrated automation system design, high voltage transmission line option, the design of lightning protection and grounding. We will compare a variety of related programs to determine the best design.35kV substation integrated automation system for unattended form, the design shall be subject to the power grid dispatching automation design, its configuration, features include the arrangement of equipment shall meet the power grid security, high-quality, layered economic operation and information transfer, the total resources the principle of entitlement.
