and operating
Reference – Control System
Instrumentation, Controls & Electrical
SPPA-T3000 Control System
offers a state-of-the-art I&C system to 16 Kaidi
Biomass power plants and enables Kaidi to
operate and monitor 16 isolated plants
remotely.
The Result
■ Central control and
monitoring of isolated
small biomass power plants
■ Reliable state-of-the-art
control system with remote
access
■ High quality operator
control due to easy
user-interface with multiple
functionality and uniform
control systems across
several plants
The Company
Wuhan Kaidi Electric Co. Ltd. is the second
biggest company in China involved in biomass
power plants. Most of those new biomass plants
are equipped with Siemens turbines and have
an electrical output of 30 MW. As feed, they use
locally abundant farm and wood waste, which
supports local farmers as well as protects the
environment. The generated power is used in
rural areas. The first plant, Hubei Chongyan
Biomass PP, has been successfully in operation
since April 2012.
auxiliary sections of the turbine at the biomass
plants.
The control systems of the small biomass power
plants at 16 different locations can be operated
from a central control room at Kaidi. Having
SPPA-T3000 in the plants means that Kaidi
operators only need to be trained for one single
system. Furthermore, the intuitive structured
interface gives the operator the opportunity to
access data and, for example, trace a history
curve by pressing just one button. Moreover
software upgrades can also be done remotely.
The whole project was delivered by an expert
team with strong technical backgrounds and
extensive project execution experience to
provide solutions for all aspects of automation
in green power generation as well as technical
support covering the plants’ entire lifecycle.
The Task
For the 16 newly constructed biomass power
plants, Wuhan Kaidi needed a reliable supplier
for the DCS for 18 units. Though the units of
those biomass power plants are small, they still
require a control system with essentially the
same functionality as one for a regular sized
plant. As the biomass power plants are mostly
built in rural regions, on-site service for these
locations is inconvenient and costly. Therefore
Kaidi needed a reliable control system that can
also be accessed remotely.
Our Solution
SPPA-T3000 Control System, the Siemens stateof-the-art DCS, was used for 16 of the new Kaidi
biomass power plants. The scope of supply
consisted of engineering, configuration,
commissioning and system integration as well
as remote service for the new control systems.
Most of the power plants are equipped with
Siemens turbines. The turbine control system
used for these is integrated in SPPA-T3000
and can be operated via the same HMI.
Furthermore, the control system automates
boilers, electrical systems, the water treatment
as well as the ash and dust removal and
“As our new biomass power
plants are built in rural areas, it
is important for us that they run
with a reliable control system
and that we can access data
from all plants at our central
control room at Kaidi.
SPPA-T3000 Control System
fulfills all these requirements.”
