Cost-Effective, Accurate Time Synchronization
Accurate time synchronization is becoming a critical requirement in today’s power system substations. For example:
- Synchrophasor measurements to support wide area monitoring systems and remedial action schemes require time synchronization accurate down to 1 microsecond
- Merging units, that publish sampled values for use by protective relays, meters, and control devices require time synchronization accuracy of 25 microseconds
- Coordinating fault records and event logs across multiple devices requires time synchronization of 500 microseconds
There are two different challenges to the traditional method for time synchronization. The first is that time synchronization has been implemented by connecting end devices to a local satellite clock. This synchronizes all elements in a specific substation together, but this may not be adequate for system wide applications like synchrophasors. The second challenge is that accurate time synchronization has required a dedicated time network.
The most common method employed which provides the accuracy required is IRIB-G. IRIG-B sends out analog pulses, which requires a dedicated analog network built on copper wiring. This network must be installed separately, and is challenged by voltage drop due to distance and the number of connected devices, as well as electrical interference. SNTP/NTP can send time synchronization signals via an Ethernet network, but does not account for switching time delays, and therefore doesn’t meet the accuracy requirements. IEEE 1588 time synchronization provides accuracy to the same level as IRIG-B, over existing Ethernet networks like NTP.
IEEE 1588 Upgrade
IEEE 1588-2008 is the technical solution designed to provide cost effective time synchronization from devices in a substation up to the whole utility grid. The challenge to implementing 1588 in a substation is interfacing with devices that only support legacy time synchronization methods. The MultiSync 100 1588 GPS Clock is a cost-effective solution to this challenge. Compact size, with DIN rail mounting, provides great flexibility in installation. Network and analog output ports allow interfacing into legacy time synchronization networks while simultaneously providing IEEE 1588 signals.
The MultiSync 100 supports common network time synchronization methods, including IEEE 1588, C37.238 and SNTP/NTP. The MultiSync 100 also supports common analog methods of time synchronization, including IRIG-B, TTL, and user defined pulse methods. The network and analog methods can be supported simultaneously in the MultiSync 100. One compact, affordable MultiSync 100 GPS Clock can provide timing synchronization for 1588 compliant devices and legacy devices in the substation, providing a simple, low cost upgrade path.
End-to-End Solution for IEEE 1588
The MultiSync 100 is part of a complete end-to-end 1588 time synchronization solution for power system substations and industrial applications. This solution includes:
- MultiSync 100 operating as a GrandMaster clock
- MultiLink ML3001/ML3100 Ethernet switches with 1588 modules
- Universal Relays and 8 Series relays time synchronized to the MultiSync 100
