The DCS can effectively upgrade the production management level in thermal power plants
at the same time
it has some negative effects to safe operation of units in the power plants.For example
the power-lossing fault in DCS can result in non-planned outage of thermal power units.The causes leading to power-lossing fault in DCS have been analysed
it is believed that the main causes leading to said fault are design in capital construction and differences in understanding.Regarding to this
a proper distributed mode of DCS
as well as alarm function of power-lossing to working power supply
by-pass power supply
and DC power supply for uninterruptible power supply(UPS)have been proposed.
