Control Systems Overview
TCL have over 30 years experience of supplying control equipment to a wide range of industrial processes. We have the expertise to be able to design and install control equipment for a wide range of industrial processes such as:
All rotating equipment including:
- Gas turbines
- Steam turbines
- Diesel engines
- Gas engines
- Water turbines
- Wind generators
Total power station plant control
- CCGT plant
- Combined heat and power plant
Power station auxiliary systems
- Water treatment
- Cooling water systems
- Burner management and interlock
Emergency shutdown systems
Water treatment systems
TCL have experience of the design and installation of systems using hardware from different manufacturers, including:
- Allen Bradley
- B & R
- GE Fanuc
The choice of hardware is often down to the customer who may have an installed base of a particular manufacturer. TCL have system integrator status with a number of hardware manufacturers, allowing us to supply hardware at competitive rates.
Most systems are installed in a retrofit environment so the layout of plant and existing inputs and outputs are fixed. I/O modules are specified to handle plant devices and environment. The I/O can be distributed around the plant or located centrally. This would depend upon the layout of the plant and cabling.
Software functionality is defined by functional design specifications which are produced by TCL. These are generally compiled using TCL expertise. However, there may be a client influence on the design where there are key local unique requirements.
A control system requires some form of human-machine interface. This may be a local HMI or a fully integrated centralised SCADA system.
Manufacture and test
All manufacturing and testing are carried out under our ISO 9001:2008 approved quality system. Systems are manufactured at the TCL works or at facilities nearer to the client's plant. We have manufactured a number of systems at overseas locations employing local labour working under TCL QA programmes.
Testing is carried out against the design specifications and will typically include:
- Hardware wiring tests
- Software I/O tests
- Software functional tests
Site installation and commissioning
TCL have an experienced team of site engineers who are available to install and commission all systems supplied by TCL. The design and testing of the system will ensure that outage times are kept to a minimum.
TCL have a dedicated customer support department to provide an after sales support of all installed system. This team are available to carry out:
- Telephone support
- 24/7 callout and fault finding
- Planned maintenance routines
TCL have the following quality control accreditations:
- ISO 9001:2008
- TickIT Guide Issue 5 software production
- CSA Z299.2-85 quality control developed for CANDU plant.
The system software is produced using rigorous quality control procedures developed during TCL’s experience with developing software for nuclear power plants.
