Electrical design, is according to design specification and the power, and load grade and capacity requirements, on for distribution system wiring figure, and line, and main electrical equipment and grounding system, from programme began, for analysis, and configuration and calculation, optimization programme, proposed preliminary design, make user audit, stay construction views returns Hou, again for construction figure design, during to and user times communication, to makes design programme maximum meet user requirements, but and not against specification provides, eventually completed to system programme of whole design process,The design of Lu-Australian company General Electric part of substation secondary system design. First of all, through research and analysis of the raw data, according to the total load compensation for transformer substation main transformer capacity. Secondly, based on the technical specification, full account of power supply reliability and economics to determine the distribution of main electrical wiring. Again, using the unitary method of short circuit current calculations, power supply design reference manuals and technical specification, select the main electrical equipment. Finally, the setting calculation of relay protection and earthing design of complete quadratic system protection, control and measuring wire drawing
