Power transmission and distribution

Use of the smartRTU remote control and automation system in a power grid  

Use of the remote control and automation system in a power grid

Application
Monitoring parameters is a fundamental requirement for the efficient expansion and reliable operation of power grids. The increasing use of distributed generation systems and the rapidly increasing number of new electricity consumers, such as in the field of electromobility, are creating new challenges. One such challenge is posed by the resulting fluctuations in the amount of electricity generated, coupled with consumption increasing as a result of applications such as heat pumps and electromobility. The electrical power distribution network must therefore be optimized to ensure reliable and future-proof operation.

Solution
The smartRTU platform was developed specifically for monitoring and controlling distribution grids. The software allows complex applications to be configured in a clear web interface. It also allows technicians to configure parameters comprehensively without any previous programming knowledge. Higher-level remote control nodes or control systems manage the reporting of operating states and measurement variables as well as all remote control operations in compliance with the latest information security regulations. The data is transmitted along several communication routes with the help of standardized remote control protocols such as IEC 60870-5-101/104 in the monitoring and control direction. Alongside monitoring solutions, the smartRTU platform executes a wide range of (remote) control commands, from simple single-point information to complex double commands with interlocks. For example, load switches and circuit breakers are controlled remotely using simple parameter configurations.

Summary
The smartRTU platform from Phoenix Contact is an easy-to-configure remote control and automation solution. The acquisition of operating data and remote control of the power grid enable operational optimization and investment planning.

Solar power

Use of a feed-in management controller in a PV power station  

Use of a feed-in management controller in a PV power station

Application
Distributed photovoltaic systems also need to play their part in high grid stability. The responsible grid operators specify the ranges to be maintained for network frequency and voltage and for reactive power in their grid connection conditions for photovoltaic systems. Furthermore, the grid operator must also be able to reduce an oversupply of energy whenever necessary. These system regulations are transmitted by the grid operator to the corresponding PV feed-in controllers using remote control technology.

Solution
Our feed-in controllers certified in accordance with VDE-AR-N 4110/20 acquire the parameters at the grid connection. The manipulated variables are calculated based on the grid operator’s specifications and are transferred to the inverters. Using this closed-loop control circuit, the PV power station performs the grid-support functions for connecting medium or high voltage. The Resy+ function block library from Phoenix Contact extends the controller in PV systems with remote control technology protocols. The diverse demands of the grid operator are implemented in connection with the modular control technology.

Summary
The feed-in controllers from Phoenix Contact meet the requirements of the test and certification guidelines in accordance with FGW TR3 and TR8. The Resy+ function block library enables reliable communication and data transmission.

Water and wastewater treatment

Use of the PumpControl solution in a wastewater pumping station  

Use of the PumpControl solution in a wastewater pumping station

Application
Wastewater pumping stations play an important role in reliable wastewater disposal. Municipal wastewater companies have distributed wastewater pumping stations spread throughout their entire distribution grid. These must, when necessary, transport the wastewater to higher-level sewage systems and function correctly around the clock. Current operating data is transmitted to the higher-level control system.

Solution
The turnkey PumpControl control cabinet solution takes over all control and regulation tasks of distributed wastewater pumping stations. Along with switching pumps selectively and recording measurement values, the controller transmits important messages to the higher-level control system via a common remote control protocol (IEC 60870-5-104, DNP3, OPC UA) and to the operating personnel by SMS.

Summary
Wastewater pumping stations can be controlled and regulated on demand by using the PumpControl solution. This saves costs and optimizes the use of resources. The integrated remote control interface enables efficient integration into the higher-level control system.

Process industry

Measurement station sensors on the pipeline  

Measurement station sensors on the pipeline

Application
A processing plant often includes hundreds of valves, some of which are still operated manually. The subsequent monitoring of these valves through the retrofitting of position switches improves monitoring capabilities and the safety of the production operation.

Solution
Smaller control cabinets with an I/O system are positioned at the center of a valve group. Two sensors are installed on each valve, which are then connected to the cabinet via cable. The control cabinet in the field is connected wirelessly to the control center with the Radioline system from Phoenix Contact. Complex proprietary coding ensures secure transmission. An intelligent mesh network increases the system’s immunity to interference.

Summary
With the modular design and the capability of incorporating a high number of devices, this system can reliably monitor small to very large systems.
