Solutions for Energy Supply

Power management 

The widespread use of electricity in all aspects of work and life offers a multitude of benefits, greater convenience and an improved quality of life. In order to ensure energy-optimized solutions in production, buildings and in infrastructures, there is a growing need for these to be based on suitable measuring systems. At the same time, the maintenance of supply security requires integrated solutions for operating grids and the standards compliant management of generating units. Bachmann offers both synergies through the direct integration in the PLC world as well as certified compliance with the latest regulations.

Smart Power Plant Controller

EZA controller, compliant with connection guideline VDE-AR-N-4110/4120 for supply

To operate a power plant (EZA) efficiently, the power management at the point of common coupling (PCC) is very important. The power plant could consist of different generation units (EZE), which are represented by combined heat and power units (CHP), photovoltaics (PV), wind turbines or storage components. A given power value could be set either manually or from a third party, e.g. direct energy trading. The resulting set-point for the different generation units in the park is calculated by the controller and then supplied to the units. According to the new requirements, which are valid from May 2019, it is mandatory for every power plant producing a power input >= 135 kW, to have a certified power plant controller, which has implemented the functionalities and follows the required rules. 

Bachmann electronic provides an EZA controller, based on the proven Bachmann CPU´s and the extremely high accurate grid and measurement module (GMP232/x). In addition to this, it completely fulfills the connection guideline VDE-AR-N-4110/4120 for power supply. The core component is the closed-loop-controller, which is a software module created by Bachmann with the extension M-Target for MATLAB®/Simulink®

This software module measures the values at the point of common coupling and with using the actual values from the park grid, it calculates the set-points and sends them to the different types of generation units. 

All the required functionalities regarding set-points for active and reactive power, also the supply of these set-points towards the generation units, e.g. CHP, are implemented. To complete this product, a local HMI is also provided. It could be used for configuration, monitoring and operation. 

This product is also shipped with a simulation library of the EZA controller for PC. This could be easily integrated into common grid simulator programs, which are normally used to certify the whole energy plant. To allow the access of direct energy trading (DET) or feed-in management signals (EINSMan), Bachmann has the most common communication protocols already included, e.g. IEC 60870-5-101/104, IEC 61850 or Modbus. These are easily to configure and beyond this, digital or analog signals could of course be used. In addition, this EZA controller solution provides the highest standards according to security, which checks and logs each and every access and change of value.


World of Visualization

One software for all applications 

M1 web.MI pro
Bachmann’s M1 webMI pro is a new product on the market that revolutionizes the world of visualization. The latest communication technologies, such as a secure web server directly installed on the M1 controller, enable the connection of any visualization devices such as smartphones and tablets but also powerful operator terminals. 

atvise® hmi
Is a fully functional Web HMI as a standard product. With many available process interfaces, a comfortable engineering tool and unlimited freedom in user interface design we contribute to shorter development cycles and cost reduction.

atvise® scada
Bachmann’s SCADA system offers a convenient and comprehensive system solution for web-based visualization projects. Maximum flexibility and openness ensure rapid implementation, good maintainability and the possibility to expand the installation efficiently. For example, the process values can be depicted fully according to the IEC 61400-25 interface. This not only simplifies internal communication but also provides external operators and energy companies with uniform access to the specific characteristic values. 

Security Integrated in the M1 System

Multi-level IT security concept 

A selective security management system not only helps with unwanted and potentially destructive hacker attacks. Particularly in the protected environment of production plants, any accidental modification of machine parameters or configuration errors in the machine network are difficult to fully exclude. The effect of these, however, is often as serious as outside threats.

Level 1: Protected network
  • Tap-proof data transmission through encrypted network connections
  • Band width limitation to defend against overload attacks and for protection from faults in the network periphery
Level 2: Tap-proof communication
  • Access control based on integrated user and password management
  • Server and client authentication for the protection of automated teleservice accesses
  • Secure end-to-end encryption to the latest state of the art (TLS 1.2)
Level 3: Authorized access control
  • Rights are examined irrespective of the access path to the controller (visualization, SolutionCenter or with OPC UA)
  • Restriction of system and execution rights for every user
  • Role-based access control with groups (users inherit group rights)
  • Configuration of access protection and visibility of files and process variables
Level 4: Hardened operating system
  • The saving and running of additional applications can be prohibited
  • Memory protection measures so that third-party processes cannot access the memory of the application
  • Detailed logging of all user accesses with all user data and partition encryption
Level 5: Secure user applications
  • Open interfaces to adapt and enhance all access control functions and for the use of cryptographic functions in applications
  • Backup and recovery mechanisms
  • Predefined security levels as templates for simple configuration

Security as standard: Bachmann protects plants from production failure caused by unauthorized manipulation with a 5-level security concept. The entire Bachmann CPU product range comes with all security functions as standard. This therefore provides the user with an optimized ready-to-use security package.
