In the fierce competition environment, students' practical ability is more important. In order to adapt to the social development, constantly promote the curriculum reform of higher vocational colleges, enhance the professional practicality of electrical control technology course, enable students to master the relevant technology and improve the teaching quality, considering the actual situation of the school, the practical course of electrical control simulation system is proposed. The control group and the experimental group are set for teaching comparative analysis. While learning theoretical knowledge, students can practice through the simulation experiment system to further improve their practical ability. The results show that adding electrical control simulation system to the teaching of motor and electrical control technology course in higher vocational colleges can greatly improve students' practical ability, and give full play to students' subjective initiative, so that they can actively learn. Therefore, the application of electrical control simulation system in the teaching of motor and electrical control technology course in higher vocational colleges is of great significance for promoting teaching reform and improving students' practical ability.
