Abstract

Disclosed in the invention is an automatic control system for a power plant. The automatic control system comprises an environment detection unit, a poisonous gas detection unit, a wireless temperature measuring unit, a dust concentration detection unit, an early warning unit, a micro processor, and a wireless communication module. The environment detection unit is used for detecting a barometric pressure and environmental humidity of a line; the wireless temperature measuring unit is used for detecting a temperature of an electrically charged device; and the poisonous gas detection unit is used for detecting CO concentration, SO2 concentration, and NO2 concentration in a power plant. According to the automatic control system, comprehensive deduction is carried out by combining various factors including the residual current, environment temperature, environment humidity, barometric pressure, dust concentration, and poisonous gas instead of by using the residual current and import part temperatures as unique criteria of alarm outputting, so that the misjudgment rate of system alarming can be reduced and the electrical fire monitoring control system of the power plant can be improved.

Description

technical field [0001] The invention relates to the technical field of automation control, in particular to an automation control system for a power plant. Background technique [0002] With the rapid development of society, a large number of electrical equipment has increased, and the electricity consumption of civil buildings has also increased year by year, and electrical fires directly or indirectly caused by electrical lines have also increased. According to relevant statistics, for example, among the 115 fires identified in 2014, 95 were electrical fires, which shows that it is imminent to strengthen the prevention of electrical fires. There are many causes of electrical fires, including short circuits, overheating, leakage, lightning strikes and electrical failures, and the fire hazards are also greater. Therefore, fires caused by various reasons should be effectively controlled. At present, protection measures such as short circuit, overheating, and lightning strik...
