Teleport

Data forwarding

All data the Teleport devices read out from your assets and instructions sent to Teleport devices can be forwarded to a destination in your own cloud. We support destinations like databases (eg. MySQL, MSSQL and Postgres), message brokers (eg. Kafka, RabbitMQ and Redis) and HTTPS endpoints. We can also forward data directly to existing monitoring and control solutions.

Forwarding process

As soon as data from and instructions to Teleport devices are received by our cloud, our forwarders will deliver it to your destination service. If that fails, for example because your destination service is temporarily offline, the forwarder will keep retrying. The delay between attempts is set at 2 ^ min(attempt, 8) seconds. Delivery of all subsequent messages is also paused until the issue is resolved. Data that is still not delivered after 2 weeks will be deleted.

At least once delivery

Messages are guaranteed to be delivered at least once, so duplicates can occur. In database systems this is overcome with unique indexes, that avoid duplicates being inserted. For HTTP and AMQP, you should deduplicate yourself. For messages from devices the combination of teleportHashId, assetIdentifier and measuredAt should be unique.

Reporting interval

Teleports are configured to a default reporting interval of 300 seconds.

Sign convention

Teleport follows the IEC 61850-7-520 Producer Reference Frame (generator sign convention) for active power, reactive power, and current.

When an asset:

  • Injects active power (generation, battery discharge, or EV discharge), the sign of active power is positive.
  • Absorbs active power (usage, battery charge, or EV charge), the sign of active power is negative.
  • Injects reactive power, the sign of reactive power is positive.
  • Absorbs reactive power, the sign of reactive power is negative.

When:

  • Active power control is set to a positive value, the asset is directed to inject active power.
  • Active power control is set to a negative value, the asset is directed to absorb active power.
  • Reactive power control is set to a positive value, the asset is directed to inject reactive power (to increase voltage).
  • Reactive power control is set to a negative value, the asset is directed to absorb reactive power (to reduce voltage).

Teleport follows the IEEE sign convention for power factor, where the sign correlates with the lag/lead convention and is based on the effective load type (inductive/capacitive).

  • For inductive loads (lagging power factor, quadrants 1 and 3), the power factor sign is negative.
  • For capacitive loads (leading power factor, quadrants 2 and 4), the power factor sign is positive.

Integrations

Integrations allow you to directly connect data from the Teleport to your favourite monitoring and control solution. Currently we have integrations with the following solutions:
