“…Two parts of energy are transferred to the ship power grid through the marine asynchronous shaft generator. In the case of ignoring the loss of the ship power grid, the total output power of the marine asynchronous shaft generator is equal to the total power consumed by all loads in the ship power grid [7,8]. e energy balance equation of the system is as follows:…”

The new type of marine asynchronous shaft generator has the advantages of adjustable excitation and power factor, compared to the traditional synchronous shaft generator, and has been widely used. However, the traditional synchronous shaft generator simulation system is still used in domestic ship power station simulators, which seriously restricts the renewal of crew training. In order to overcome the shortage of the simulation system of doubly fed shaft generator for ship power plant simulator, in this paper, the mathematical model of marine doubly fed shaft system is established for the first time, according to the characteristics of doubly fed machine and marine shaft generator. This paper realizes power decoupling by stator flux orientation and simulates and analyses the asynchronous shaft generator under subsynchronous working conditions. The changing trend of each physical quantity in the simulation waveform meets the mathematical relationships of the actual physical quantity, which proves the correctness of the mathematical model and lays a theoretical foundation for the development of the simulation system of asynchronous shaft generator.

“…Furthermore, in the coming energy internet, more and more plug and play units such as new energy power generation would be introduced to the grid, then so many types of energy input are integrated together, higher challenges are presented for the maintenance and enhancement of power quality of power grid [1,[9][10][11][12]. Research on power quality conditioner has been carried out extensively [13][14][15][16]. Key units such as DC support unit and filtering unit have been deeply studied by researchers as well [17][18][19].…”

Power quality issues have become one of the most important issue for researchers to concern. In this paper, simulation and experiment of algorithm and circuit design of Unified Power Quality Conditioner (UPQC) are provided. Control algorithm and topology design of one UPQC which includes active power filter (APF) and dynamic voltage restorer (DVR) are introduced. Stability condition of the filter unit is deduced and proved by Routh stability criterion. Simulation for APF and DVR is carried out in PSCAD to show the proposed control strategy. Experiments such as current tracking, harmonic detection and compensation and voltage drop compensation are provided in details. Experimental results show that the proposed control method and the designed topology are effective and practical.
