E²CON-CHP

The flexible system for engine,
generator and all auxiliary units

The further development of gas engines and new cogeneration plant operating concepts demand a flexible engine controller. One that can keep the engine operating safely at the limit of its mechanical performance while at the same time integrating it seamlessly into the cogeneration plant or into a whole network of plants.

Based on our flexiblehardware and software components, the E²CON-CHP creates a control system for the entire CHP modules including the gas engine. For typical applications we already have tried-and-tested configurations - from circuit drawings to system visualization.

With our modular principle, you implement the control for engine, generator and auxiliary units up to central SCADA systems with just one concept. Ultimately, you decide what we deliver: The standard application or a solution ready adapted to your requirements, on which our or your developers can continue to work.

MWM / Deutz Retrofit
engine control system

E²CON-TE

Familiar system
with latest state of technology

With the experience we gained on well over 10,000 engine controllers for DEUTZ and MWM gas engines, we are confident we have designed the optimum solution for their modernisation. Taking current needs into account and anticipating future challenges. This new engine management system is based on the lastest technology, and is conceived as a risk-free conversion for replacing the TEM-Evo controllers that were delivered as standard equipment on DEUTZ and MWM engines.

New plant concepts and operating modes demand a flexible engine control system that on the one hand can manage operation at the engine's mechanical limits and on the other hand enables an engine to be quickly and simply adapted to new requirements.

Advantages AVAT E²CON-TE

  • Simple commissioning
    TEM-Evo-trained service technicians can exchange the system themselves, commission it and adapt it the plant
  • Delivery
    of a complete scope-of-supply including circuit diagram, installation instructions, functional description, list of limit values and parameter descriptions
  • Web Interface
    to the E²PILOT workstation for direct insight onto the controller from any web-capable client
  • Optional Connection
    to the AVAT VIRTUAL SERVICE CENTER for an overview of all connected plants and to an alarm management system with live status
  • VHPready
    for straightforward integration of the plant into a virtual power plant, without the need for an overriding control system to cover this function

Statement of Conformity: For the use of E²CON-TE according to Code of Practice VDE-AR-N 4110 (TCR Medium Voltage), a certified proof of TEM-Evo equivalence is available.

Modernizations with E²CON-TE do not represent a significant change compared to the MWM series control system. Engines and plants previously controlled by TEM-Evo behave uncritically with regard to the electrical characteristics after retrofitting with E²CON-TE and show the same behaviour with the same parameterisation. With E²CON-TE afterwards is like before - contact us for further information!

Plug & Run Retrofit
Fast and simple system update by means of a pre-configured control cabinet for direct installation on site. Generator-set cabling can be retained and only renewed when "natural" degradation dictates.

Parameter Conversion
The risk-free update is achieved via a unique parameter converter. The system's major control functions, such as start/stop, emissions control and control of peripherals behave the same after the retrofit as they did before. In this way AVAT optimally minimizes the risk that the modernization of a competitor's system could lead to a deterioration in control functions.

Smart Communication
The connection to the E²PILOT workstation and to E²SERVICE service tool no longer involves serial interfaces but are completely ethernet-based. This enables simultaneous operation.

Extended Parameter Accessibility
More scope for individual system adaptation and expansion to specific operating conditions. The familiar control functions of TEM-Evo have been further optimised and are available in their accustomed quality.

Optimised Operation
The familiar operating concept as well as the parameter views are retained. With the new operator interface of E²PILOT, anyone who knows the earlier system will soon be at ease and confident enough to start work. In addition, with E²SERVICE service technicians have available a comprehensive service and diagnostic tool.

Safety concept

Based on our unique system integration platform for gas and dual fuel engines, E²CON-M is completely flexible, scalable and open to any kind of extension. Functions, modules and subsystems form one unit with a powerful user interface.

E²CON-M is integrated into the ships automation and consists of three units. The control panel with an engine control and alarms module combined with an engine safety system, the auxiliary panel and a technology component to control combustion characteristics. The control architecture is based on an industrial controller. All modules and devices operate according to the principle "smart sensor" and "smart actuator". They deliver pre-processed information and are controlled and configured by the PLC. All control and monitoring functions access the same data and thus all data is usable in the total system and is displayed on the user interface.

The reinforced cabinet of the control panel and the combustion control unit are vibration-damped mounted on the engine. Wiring of sensors and actuators is directly connected to terminal blocks inside the control panel. As third unit the auxiliary panel is placed away from the engine to simplify wiring of auxiliary inputs and outputs. Redundant Ethernet and CAN connections ensure high operational safety.

  • Fuel-sharing mode
  • Diesel-gas switchover even at high load operation
  • System fulfills requirements for multi engine power generation
  • Cylinder pressure based engine control and monitoring
  • Balancing strategies based on identified combustion parameters
