  • Cascaded network power control system
    Publication number: 20040007917
    Abstract: The present invention provides a cascaded network power control system comprising at least a controlled power site and a control center. The controlled power site has a front end processor (FEP). The FEP at least has two network ports (an uplink network port and a downlink network port). The control center uses an optical fiber to connect the network ports of the FEP, and uses the network ports of the FEP to establish contact with another controlled power site. The network ports are connected with network ports of a preceding controlled power site and the next controlled power site for transmission of a normal/abnormal signal of an intelligent electricity device (IED) of the preceding controlled power site. The normal/abnormal signal is transmitted to the IED of the local controlled power site via an RS232 or RS485 port.
