From the perspective of harmonic constraints, this paper analyzes the access capacity and access mode when the distributed generation is connected to the power grid, and puts forward the mathematical model for calculating the maximum access power of the distributed generation. Combined with a typical chain distribution system, matlab simulation calculation and FFT harmonic analysis are carried out, so as to obtain the maximum access power of the distributed generation at each point along the feeder when a single distributed generation is connected. It is of great significance to reasonably plan the distributed access location and access capacity in practical engineering.

In view of the immature control system of permanent magnet brushless DC motor and the instability of the control system, this paper proposes a permanent magnet brushless DC motor based on phase advance correction controller, designs the controller to realize the closed-loop automatic control of the system, and proves the effectiveness of the control strategy through modeling and simulation, so as to solve the instability of the control system.
