ME 4012 PA-N small telecontrol system
ME 4012 PA-N small telecontrol system provides information from medium and low voltage grids
Deregulated energy markets and financial incentives for small and medium decentralized power generation plants enacted by state legislation require a new assessment of the aspects of power system planning in the future.
To provide grid operators (grid control and planning) with even more information from the medium and low voltage grid or gas pressure regulating stations, Mauell GmbH developed a new modular small telecontrol system capable of meeting both present and future customer needs.
This small telecontrol system (SmartRTU) links new hardware components matched to the specific environment to the existing software functionality used in today's transport and distribution systems of modern utility companies.
The ME 4012 PA-N system's current CPU provides three different physical communication interfaces (Ethernet; Serial RS232; Field bus RS485). Communication via these interfaces is based on standard transmission protocols IEC 60870-5-101; 3; 4 Modbus TCP Client or Modbus RTU (Master / Slave), depending on the system specifications.
Communication based on IEC 61850 will be available by the end of 2012. The implementation of additional transmission protocols is being planned.
The device offers different power supply cards (24-220VDC /230VAC) with 24VDC auxiliary voltage and communication cards (RS232 or Ethernet) for expanding the system’s interfaces.
ME 4012 PA-N offers versions of different system extent. The device is contained in a stainless steel housing of 146 mm width providing 3 free slots or 209 mm width providing 6 free slots. It is 99 mm high and 132 mm deep and can be used both as add-on and built-in unit.
For larger telecontrol applications, a 291 mm wide add-on unit with 12 free slots is available.
The free slots of an ME 4012 PA-N system can be equipped with different input and output cards.
The following cards are currently available:
The system's parameters can be defined online by means of a Web server integrated on the CPU, or offline using an external tool (from 2013). To protect online connections via Ethernet or USB interface from unauthorized access, a firewall meeting with BDEW Whitepaper requirements has been implemented. All firewall parameters can be defined via the Web interface. If required, the system can be equipped with an external storage medium (SD card) for backing up parameter settings and archive values for service tasks.
In addition to the basic applications, a variety of industry-specific automation solutions for the electricity and gas sector are available that can be integrated via the Web interface.
Our ME 4012 PA-N has been designed with a special focus on the implementation of quality tested coordinated customer parameters for a large-scale production and easy maintenance and parameter definition.
To ensure that ME 4012 PA-N can be optimally integrated into a customer-specific overall solution comprising communication terminal equipment (GPRS, radio transmission, DSL, optical fiber, etc.) and industry-specific equipment (e.g. integration of ES-KU direction indicators), function tests with selected manufacturers have been conducted as a way to complement ME 4012 PA-N systems with respect to data management and parameter definition functionality and compatibility. These specific devices can be found in the Accessories section of the system's product catalog.
