As a means of quickly learning operational skills for thermal power plant facilities or
passing skills to successors, operational training simulators with human machine interfaces and
plant models that can recreate the same behavior as actual plants have been utilized at power
plants and training centers. Recently, however, several plants had incidents caused by abnormal
water quality, disturbing the stable supply of power. In terms of existing operational training
simulators including the products of Mitsubishi Heavy Industries, Ltd. (MHI), there is room for
improvement in training programs dealing with water quality-induced problems, and there are few
incidents of actual problems occurring. It is therefore expected that the development and use of
water quality simulators for thermal power plants, which can provide training programs in terms
of operational procedures for abnormal water quality, can prevent the serious problems resulting
from abnormalities in water quality, and shorten the duration of plant shutdown necessary for
repair and restoration. This report gives a summary of our water quality simulator for thermal
power plants, which is useful for operational training to handle abnormal water quality-induced
problems.
