Simulation is always the first step in the design of power converters. To maximally make the simulation results close to the experimental results, accurate models of all passive and active elements are necessary, which are the precondition for validating the expected behavior of the complete system including its converter topology and control algorithm without any prototype. For this reason, due to...
In order to achieve online monitoring the downhole information related to ESP working state, an ESP downhole parameters monitoring system based on current loop data transmission method was developed. Compared with other methods, the current loop data transmission method was relatively insensitive to interference in harsh environment. By means of ESP motor's winding and symmetrical reactance located...
The paper conducted a theoretical analysis and simulation research on the control strategy of STATCOM based on modular multilevel converter (MMC). Precharging control strategy, capacitor voltage balance control strategy as well as STATCOM control strategy are proposed. According to the simulation model of SVG, the strategy proposed is proposed. The control methods are tested with the help of PSCAD.
