- Case Studies
The power plant commissioning process takes account of all elements of the Design and Functional Specifications to ensure all elements of the system operate as designed, and interface with the entire system completely.
Whether the Scope of Supply includes a single generating unit, combined heat and power (CHP) plant or a full turnkey project, our Commissioning Team is responsible for the commissioning and setting into safe operation all equipment and services supplied as per the Scope of Supply.
Dependent upon the Edina Scope of Supply the Commissioning Process normally falls into these key areas.
Many pieces of equipment or services are tested to ensure that energisation of a building or system can take place safely.
Commissioning of the generating unit or CHP plant is completed to ensure that all systems are safe to energise and are completed before the unit is started.
Additionally, throughout this stage all systems and equipment external to the generating unit or CHP plant is inspected and tested to ensure all systems are safe to enter operation.
The generating unit or CHP plant is started and all checks relevant to safe operation and synchronisation of the unit against the electrical grid are carried out to include:
Once the generating unit or CHP plant is capable of grid synchronisation, it is brought up in load stages according to recommendations set by MWM and Edina. The load stages are carried out in isolation from any site system to ensure the generating unit or CHP plant can attain full load capability.
During this process and at each load step, the engine, alternator and system pressures, temperatures, exhaust emissions and performance is checked with calibrated equipment and the results are recorded and verified against stated performance criteria.
The generating unit or CHP plant is then ‘opened up’ to the sites systems. At this stage, the performance and output of the unit is checked against agreed performance criteria, thermally and electrically, and any adjustments or trimming of the control systems is carried out. This includes a period of ‘normal’ operation against all site systems.
Once complete, the generating unit or CHP plant is subjected to an internal ‘trial’ performance test to ensure that all Contractual Performance criteria is met, including:
In accordance with Contract Conditions in place, the generating unit or CHP plant is then subjected to the agreed Performance Tests. These would normally replicate the ‘Trial’ tests completed. The timing and duration may vary according to the individual customer requirements.
Providing all the necessary tests and inspections have been passed satisfactorily, the generating unit is ready to enter commercial operation. This may initially be in the form of an extended reliability test period, e.g. 28 days.
At the time of Handover to the End User, the Commissioning Team will complete the Operator familiarisation Training, the purpose of this is to, familiarise Site Staff and Operators in the Safe, Routine Operation of the Edina Supplied Equipment installed.
Our Commissioning and Project teams are involved at the point of Sales handover. During Project Progression, the Commissioning Manager, together with the Design and Project Teams, produce a dedicated Commissioning Documentation package to suit the individual project installation and meet your strategic requirements.
