摘要
运用计算机辅助设计和多变量系统频域控制理论,设计了一个交流变频调速电动机-发电机组的自动跟踪同期闭环解耦控制系统,计算机仿真表明,本系统可实现发电机端电压矢量的幅值、频率和相位无静差地与电网自动跟踪同期;同时,机组能在电网电压、频率波动的情况下,仍快速而平稳地实现同期.
By using multivariable control theory in frequency domain and computer-aided design technique, a closed loop decoupled control system for automatic following synchronization of a variable frequency speed control A. C. motor-generator system is designed in this paper. Computer dynamic simulation shows the voltage vector of the generator can follow that of the power system without static errors in magnitude, frequency and phase angel. The generator can also be synchronized with the power system smoothly and quickly, even if the voltage and frequency of the system are fluctuating.
