Abstract:

Since the relatively dispersed layout of a winch hoists in a hydropower station, it is difficult to realize centralized control by  traditional control system. There are complex wiring and fault nodes on site, which leads to poor antiinterference ability. After the research on PLC and Ethernet bus communication technology, a winch hoist control system  for hydropower station is develped based on Ethernet communication technology. The technology  reduces the number of wires on site, improves the antiinterference ability of the system, realizes graded automatic control on gates, reduces the operating staff and increase the control distance, advances the humancomputer interaction performance, and improve the automation and stability of the system, which provides reference for the design of winch hoists for hydropower stations.
