| Popis: | 96 This thesis presents an integrated analysis program and supervisory control using Ethernet-RS485 bidirectional interfaces for industrial power distribution systems, which improves efficiency and coordinating mechanism among planning, manipulation and management. Based on the Bus Impedance Matrix building algorithm, the proposed software program organizes power flow analysis, short circuit capacity calculation, simulation of large motor starting characteristics, and power factor correction into a multi-function integrated program, which is superior to several mono-function conventional programs. All functions are operated in a user-friendly man-machine interface environment which includes two major visual windows of element-data and icon-control. Numerical analyses in the default graph-text format are displayed on the output windows such that the user can observe or revise the system real time. In addition, in order to implement a theoretical case, this dissertation combines the high expanding advantage of Ethernet with the long-range transmitting characteristic of RS485 to perform a data-collecting integrated circuit, Ethernet-RS485. In industrial power distribution systems the integrated circuit with a star-type topological structure is used to execute supervisory control accurately, speedily and effectively. |
