Abstract：The measuring control and protection device was designed for the low-side of box-type step-up trans-former in wind farm, the 32-bit ARM processor MB9BF618 was used as a core component in this device, it could realize the measurement of electrical parameters such as voltage, current and power, and the device had the func-tion of protection such as three-phase current protection, overload protection, zero-sequence protection. The schematic diagrams of the signal sampling circuit, switch signal input/output, communication interface were giv-en, and the detection algorithm of AC signal, test results, matching method of protection were introduced. This de-vice had the features of complete functions, easy protection configuration and high reliability, which could realize such tasks as measuring, protecting and controlling for the low-side of step-up transformer in wind farm.
