ENGINE & CHP CONTROL

Product catalog summary

Overview
The document outlines the AVAT Engine and CHP Control system, a flexible solution for managing engines, generators, and auxiliary systems using the openECS platform. It offers a customizable approach, allowing for either standard applications or tailored solutions.

Compact System Layout
The system uses compact modules, reducing space requirements by 50% compared to conventional layouts. EPLAN libraries and circuit diagrams are provided for all components.

Grid Protection
Integrated grid code functions and generator protection are included. The Bachmann GSP274 modules simplify gen-set certifications, with support available for certification processes.

Comprehensive Scope-of-Supply
The AVAT Standard Application includes circuit diagrams, installation instructions, functional descriptions, and parameter lists. It supports the integration of gas engines into cogeneration plants or networks.

Controller Features
The system offers a robust multi-variable closed-loop controller, rapid engine run-up, wastegate control, grid protection, diagnostic tools, and adaptability. It ensures long-term spare parts availability and uses proven technologies.

Functions
Key functions include closed-loop control of engine speed, power, and air/gas mixture, start/stop sequences, wastegate control, knock control, misfire detection, sensor monitoring, and cogeneration plant control.

Additional Components

E²KNOCKCON-c20: Detects combustion knock and misfiring.
E²SERVICE: Software for service technicians for commissioning and maintenance.
E²CORE-control: Multi-variable controller for throttle and wastegate control.
AVAT Router MDH814: VPN router for remote access.
Bachmann CPU and I/O: Industrial controller and expandable inputs/outputs for engine management.
Bachmann GSP274: Grid monitoring and generator protection.
E²PILOT: User terminal with touchscreen for plant operation.
AVAT VIRTUAL SERVICES: Central management of engine pool and service staff.

openECS Platform
The openECS platform is a flexible engine controller for gas and dual-fuel engines, allowing for expansion and integration of various devices. It combines special engine control components with a modular industrial PLC for a future-proof solution.

Areas of Application
The system is suitable for engines and actuators from various manufacturers, using natural gas, biogas, or special gases, with outputs ranging from 250 to 2000 kW. It supports stationary cogeneration plants, containerized systems, and installations in permanent structures.
