Telecontrol Connection for Customer Substations

The master/slave concept (primary/substation) of the KÜS enables projects with two or more separate controllers. The primary station is the central controller, acting as a gateway to the network operator. It collects system data and provides it via an IEC-60870-5-104 interface. The substations record system data and forward it through the internal bus system to the primary station, which assumes control. The system is VDE-ARN-4110 certified and supports the connection of PV systems, direct marketers and grid operators. Substations are primarily used for recording digital signals.

A cascaded power plant system at the customer substation enables flexible control by a central power plant entity. This central entity accepts setpoints from the network operator and direct marketer, forwarding them to lower-level entities. The system can operate on one or more KÜS controllers and supports applications such as prioritizing PV systems, integrating various types of data loggers and providing separate producer data to network operators or direct marketers. Only the central entity assumes control in the closed-loop method, while the lower-level instances pass on the setpoints.

The current version of the application supports connections to numerous signal conditioners, data loggers and inverters. If needed, the inverter can act as a measurement source, and control data – such as active and reactive power and voltage from different sources – can be combined. A 3-phase power measurement module, compliant with VDE-AR-N 4110 standards, controls PV systems.

Power plant controllers help power plants achieve grid-compatible feed-in management at the grid connection point (GCP).

WAGO Power Plant Control allows plant operators and system integrators to meet the requirements for these controllers that are set on the grid side – flexibly and reliably. The solution is certified per VDE-AR-N 4110 and 4120.

The world’s fossil fuel supply is finite, and global warming is already well underway. Failure is not an option for the energy transition. Telecontrol technology will play a special role in the implementation, since the electricity, gas, water and heat infrastructures in particular involve spread-out service areas and remote stations.
