Time Synchronisation for Power

The Meinberg modular time synchronisation system, available from APC Time, can be configured to a mix of outputs for different devices including IEDs and SCADA systems.

Our IMS (Intelligent Modular Synchronisation) platform provides the ability to select a combination of IRIG timecode outputs, pulses and frequencies to suit substation component requirements. In addition, NTP/SNTP as well as PTP network synchronisation interfaces can be added, making it the a perfect choice for substation automation and smart grid applications like synchrophasors and event recording.

The 1U rackmount LANTIME M1000 can play different roles, depending on its configuration and module selection. Supported by Meinberg‘s IRSA (Intelligent Reference Switching Algorithm) technology, the M1000 can use GPS, GLONASS, 1PPS or IRIG time codes as its synchronisation sources and can also accept PTP and even NTP in a user configurable priority.

The PTP implementation supports the PTP default profile (IEEE 1588-Annex J) as well as several power profile versions, including IEEE C37.238-2011. The Utility profile as standardised in IEC 62439-3 Annex B is also supported.

PTP Synchronisation

If desired, a second TSU module can be used to synchronise the LANTIME M1000 with a remote telecom profile grandmaster over a wide area network link. The performance of the TSU module allows to synchronise hundreds of IEDs or other PTP slaves when operating as a power profile or utility profile grandmaster clock.

NTP Synchronisation

For (S)NTP-based synchronization, the CPU and the TSU modul network interfaces of the LANTIME M1000 can be configured to act as a NTP server. The TSU Carrier Grade NTP mode offers a 10 ns time stamp accuracy, and serves up to 12000 NTP requests per second while the Software NTP service of the CPU module supports up to 10000 requests per second with sub-millisecond accuracy.

Below is a sample LANTIME M1000 configuration that provides various time code, pulse and frequency outputs on both electrical and optical interfaces.

The modular approach of the IMS platform allows field-replacement and hot-swap capability for IO modules and power supplies. This concept future-proofs your technology investment by allowing you to add or replace modules when new technologies or interfaces are required and makes this product one of the most scalable and flexible synchronisation solutions on the market.
