The AC/DC integrated power supply of substation consists of the substation AC power supply, DC operational power supply, UPS and communication power supply, etc. Based on DC power system, all its sub-power systems are under unified design, planning, O&M and. Integrated power distribution system in a free-standing enclosure, with or without aisles. Abstract: As a necessary power source for substations and other important power-using places, substation power supply system provides working power for important loads such as control devices, relay protection, communication equipment and fire security systems. The first volume in our series "Planning of Electric Power Distribution – Technical Principles", focused on general. As defined in the International Electrotechnical Committee (IEC) 61850 standard, digital substation architecture comprises three levels: a process level, a bay level and a station level, as shown in 2. According to the problem that the intelligence is not high of the soccer robot, using the mechanical theory as a guide, making some mechanical analyses and calculations on the pressure and transmutation states of chip kick mechanics, and conducting optimal design too, then making the structure of.
