Thailand’s National Energy Policy Council approved Power
Development Plan (PDP) 2018, which requires that power
generation capacity be increased from 37,612 MW in 2014
to 70,336 MW in 2036 to meet forecast economic growth.
At the same time, however, due to increasing air pollution
and the depletion of domestic natural gas resources, PDP
2018 also directs power generation companies to improvefuel efficiency. Gulf JP Nong Saeng Power Plant (GNS), oneof the biggest power providers in northern Bangkok, waschallenged to not only improve efficiency in all operation
modes, but also meet the flexibility demands of a dynamic
power generation market.

After implementing the TOMONI Edge Enabler with IGV
Optimization in June of 2019, GNS experienced a heat rate
improvement of 0.67% at 450 MW load, 1.60% at 590 MWload and 0.34% at 770 MW load, and the unit performed
well during both governor control mode and frequency
response mode.

GNS worked with Mitsubishi Power todevelop a plan to improve the plant’s
efficiency and flexibility. The team
decided to install the TOMONI Edge Enabler (MTEE), an edge
solution used to manage software service applications. TheTOMONI Edge Enabler gave the plant a very flexible way toimplement the TOMONI IGV Optimization solution to improvefuel efficiency, especially during periods when the plant isrunning at partial load.
Through communication with the existing Netmation
control system, IGV Optimization provides real-time
optimization that closes the gas turbine inlet guide vanes
to optimally control airflow at part loads, increasing
exhaust temperature while reducing emissions. Pairing IGV
Optimization with the TOMONI Edge Enabler, an operator
receives guidance from advanced analytics and can engage
or disengage the software, giving GNS the ability to obtain
early validation of the economic benefits and utilize the fuelefficiency solution only when it provides benefits.

DATA FOUNDATION& ENABLERS

In addition to IGV Optimization, the TOMONI Edge Enabler
can also manage a family of other software-based
solutions, providing additional opportunities for increased
output, efficiency and flexibility with selective validation
and application of solutions as the power market evolves.

Gulf JP Nong Saeng
Power Plant“Since the rapid growth of renewable generation in Thailand,
the Nong Saeng Power Plant has become one of theimportant generation sources to support the grid during
output variations of these renewable generation sources. As
a result, our plant is now dispatched regularly to operate atpartial load. Originally optimized for full-load efficiency, weworked with Mitsubishi Power to find ways to operate more
flexibly and efficiently at partial loads. The combinationof the TOMONI Edge Enabler with IGV Optimization wasmatched to our need for cost-effective improvement inpartial-load efficiency, to reduce our fuel costs. With theTOMONI Edge Enabler our operators can engage the IGV
Optimization when it has the most economic benefit, anddevelop the criteria for future automatic operation.”
