But, a lot of distribution on-line monitoring systems do not arrange the system of clock synchronous because of factors such as technology, only system equipment is arranged separately respectively to clock, thereby cause the interior equipment clock of system asynchronous, the monitoring of distribution line and fault analysis are had to larger time delay, increase the time of fault handling, reduced the reliability and stability of operation of power networks.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of distribution on-line monitoring system based on big-dipper satellite clock synchronous, solve distribution on-line monitoring system network and because equipment clock is asynchronous, cause the problem of time delay, improve the reliability and stability of operation of power networks.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of distribution on-line monitoring system based on big-dipper satellite clock synchronous, it is characterized in that: comprise distribution on-line monitoring system and the PTP time server based on the Big Dipper, described distribution on-line monitoring system comprises monitoring device and main station system, and the described PTP time server based on the Big Dipper obtains the time reference of the Big Dipper and sends to monitoring device and main station system.
Preferably, in the described PTP time server based on the Big Dipper, be embedded with IEEE1588 protocol module, this IEEE1588 protocol module sends to monitoring device and main station system in the mode of broadcasting packet by the time reference of the Big Dipper.
Preferably, the described PTP time server based on the Big Dipper utilizes RS232 interface to receive the signal that big-dipper satellite sends.
The main station system that the utility model is on-line monitoring system by big-dipper satellite and each monitoring device under main station system provide synchronous clock, can not only realize fast on-line monitoring and localization of fault, and well solved the latency issue of interactive device in existing distribution on-line monitoring technique, improved the reliability and stability of operation of power networks.In addition, owing to adopting high-precision IEEE1588 agreement, carry out time service data transmission, traditional NTP, the not high problem of SNTP agreement time service precision have been solved, once there is fault in circuit, can accurately locate, shortened the time of breakdown repair, improved power supply reliability and stability, for the safe and reliable operation of digitizing distribution provides basic guarantee.
