Energy Manager 1.3 - Instruction Manual

Energy Manager Software Modules
The Energy Manager comprises various modules which adapt to the
customer’s needs. The modules are related to specific hardware
components and implemented into the Energy Manager when agreed with
the customer.
In this chapter an overview of the following modules is given. This
overview may not correspond completely to every customized solution.
Genset Management Module
The genset management module controls the diesel generator.
Depending on the system status, the generator is switched on or off. In
order to increase genset efficiency, maintenance, and reliability, the
runtime can be split between different generators and up to 2 genset
management modules can be implemented.
Several generator state variables are monitored: the starter battery voltage
and variables depending on the generator controller hardware like the
coolant level, coolant temperature, and oil pressure. Optionally, a
generator oil management system can be installed and controlled.
Fuel Management Module
The diesel fuel management module monitors data related to the fuel tank
like the measured tank level and related variables such as fuel loss, fuel
refill, total consumption.
Battery Management Module
The battery management module controls the charging and discharging
of the connected batteries. It monitors battery state variables like voltage
and current of the whole battery string, symmetry voltage, state of charge,
state of health, depth of discharge, capacity, battery temperature. Up to
12 banks, each with up to 6 strings can be implemented.
Aircon Management Module
The aircon management module controls the connected air conditioners.
The air conditioners are switched on and off depending on the measured
temperature and selected control algorithm. Different aircon units can be
cascaded in order to start one air conditioner after the other depending
on the required cooling capacity. The runtime of the air conditioners is
logged.
Site Management Module
The site management module monitors general state variables affecting
the whole site, like grid, ambient temperature, humidity, and delivers
alarms like gate, fence, and shelter alarms.
Load Management Module
The load management measures the voltage and calculates the power.
The total energy consumption is calculated in kWh.
