Computer controlled wind power plants application with induction generator (AEL-WPPIC)
PL-640396
The Computer Controlled Wind Power Plants Application with Induction Generator, “AEL-WPPIC”, developed by EDIBON, is designed for the study of the characteristics and behavior of induction generators used in wind turbines that inject power into the grid. The application provides users with the opportunity to explore the electrical schemes and operational features of wind turbines that utilize three-phase squirrel cage rotor generators in wind power plants.
The AEL-WPPIC application includes a squirrel cage induction generator coupled to a three-phase motor (turbine), with the motor’s speed regulated via a variable frequency drive. The system simulates various wind conditions and the drive train of a wind turbine. The unit also incorporates a turbine controller that automatically controls the electrical parameters and speed of the turbine-generator group, in addition to performing the automatic synchronization of the three-phase induction generator with the grid.
This control module also serves as an advanced protection system for both the generator and the turbine, meeting ANSI protection standards (ANSI 81O, ANSI 81U, ANSI 59, ANSI 27, ANSI 50/51, ANSI 32R/F, ANSI IOP 32, ANSI MOP 32, ANSI 46, voltage asymmetry, generator ground fault, phase rotation, and generator lagging power factor, among others). Additionally, a three-phase capacitors bank is included to generate the necessary reactive energy to prevent the induction generator from consuming it from the grid. A network analyzer monitors the generation’s electrical parameters.
The core of this application is the wind power plant simulation software, “PSV-WPPP-SOF”. This software allows users to remotely control and automatically synchronize the turbine-generator group, while monitoring various generator electrical parameters, energy losses, and voltage drops. It also enables users to save and compare data for later analysis. The software provides accurate insights into the effects of reactive power compensation, energy demand, load unbalances, and the power factor variation.
Moreover, the PSV-WPPP-SOF software offers the capability to simulate pre-configured wind curves for real-time or later analysis of the induction generator's response. Users can examine the speed and power curves of the simulated wind turbine based on pre-configured values, facilitating a comprehensive study of wind power plants.
For additional learning, it is recommended to acquire modules for the study of island operation of the three-phase induction generator, along with manual compensation of reactive power. The analog instrumentation module for measuring key electrical parameters (P, Q, V, f) of the generator is also recommended to enhance the study.
