Rational Synchronous Electric Drive of Agricultural Pumps
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
This article discusses design and mathematical description of rational synchronous electric drive of portable irrigation pumps. This electric drive makes it possible to decrease wasteful energy loss for irrigation due to improvement of energy performances of electric drive. Electric drives of irrigation pumps are the most energy intensive power consumers in agricultural industry, which often operate from long distance power transmission line, improvement in their energy performances decreases power loss both on the drive itself and in supply line. Power supply line for irrigation purposes usually operates with the voltage of 10 kV, whereas the voltage of rational motors for pump drives is below 1000 V. Under such conditions it would be reasonable to operate transformer–motor assemblies, which optimize control and protection of pump assemblies. Such assemblies enable rationalization of control device of synchronous motor in pump drive by simplifying exciter with retention of automatic excitation control in function of mechanical load and motor supply voltage. This article presents mathematical description of transient and steady electromagnetic processes in transformer–motor assemblies of the considered design.
