That is, 1, choice of the main transformer substation of the models, capacity and number of Taiwan. 2, the design of the electrical substation main connection of the basic form. 3, a short-circuit current calculation. 4, a major electrical equipment choice. 5, the high-voltage pow
4、er distribution substation planning and design of the devices. 6, the substation protection and automatic devices of the planning and design. 7, Lightning Protection of the substation planning and design, such as seven steps, this paper with the electrical design on a point of order. The design is i
5、n school during the last a very important part of a comprehensive practice teaching, but also full use of our students have learned basic theories, professional knowledge to practical problems to design (or research) integrated training, is also our future Jobs and to lay the basic practice. Through
6、 this design can be enhanced by the knowledge we use to explain the actual capacity and ability to innovate in order to better meet the needs of their work. The design elements associated with the reference to the preparation, the limited level, it is inevitable there will be errors of omission, please refer to the teacher to give more criticism correction.
