Microturbine Generation System
Microturbine unit (MTU) is well suitable for a different distributed generation applications, because the MTU is flexible in connection method, can be stacked in parallel to serve larger loads, can provide reliable power and has low-emissions profile. peak shaving,
premium power, remote power, and grid support are the applications of MTU. The MTU is operated in
off-grid mode in the case where power from the local grid is
unavailable or extremely expensive to install, or the
customer is far from the distribution system.
MTU Configuration
The major components of the MTU are:
single-shaft turbine with its control system, high speed
permanent magnet generator, power electronic
interfacing (rectifier and voltage source inverter) and
control system for power electronic interface.A loseless DC
bus is assumed. Microturbine is equipped
with controls that allow the unit to be operated either in
on-grid, or off the grid mode.
Modelling of Microtubine:
The model includes the temperature
control, fuel system, turbine dynamic, speed governor
and acceleration control blocks.
Power Electronic Interface
This part consist of a rectifier-inverter
system with DC link. Power
electronic interface in the single shaft microturbine is a
critical component. and is a general configuration of
power electronic interface in the MT units.
in order to achieve the
required total system capacity, all the MT units are connected in parallel. base
loading and peak shaving and grid support are provided by the MTU in the on grid mode. off-grid mode means MTU is completely isolated from the grid.
ON-GRID OPERATION:
Here, the inverter must regulate the DC
link voltage at 0.75 kV, and control the active and
reactive powers injected into the AC grid,taking the set power and voltages into consideration.
OFF-GRID OPERATION:
Here, the MTU should supply AC loads, such
as sensitive, nonlinear and unbalanced loads.
