摘要

本文介绍了一种基于简化摄动和观察（sp & & O）的控制方法，旨在管理三相/单相交流负载与可调节直流负载之间的功率传输，该负载由三相隔离感应发电机（IIG）供电，该发电机与偏远山区的不受控水轮机相连。控制器的有效运行依赖于传感器的精确反馈，传感器作为输入信号。具体来说，两个传感器——一个测量电压，另一个测量电流——被用来为实时实现（RTI）平台提供输入。AD202KY电压传感器位于IIG的PCC (Point of Common Coupling)， LA55-P电流传感器测量交流负载电流。为了提高信号质量和控制反馈电压，额外的信号调理电路（SCCs）使用基于运算放大器的TL084和LF353分别连接到电压和电流传感器。这些SCCs消除噪声信号，确保最佳性能。此外，我们建议三相IIG的外部激励方案，其中包括单个电容器（1CS方案），以实现单相家庭供电。采用dSPACE 1104作为RTI平台，在两个不同的额定功率为2.2 kW和1.5 kW的三相415 V机器上成功地测试了所提出的功率传输控制方法，采样时间为1ms。重要的是，所提出的方法表明，在突然主负载应用中，国内负载的功率波动和终端电压振荡减少，强调了其在确保平稳功率转换方面的有效性。

Simplified P&O based MPPT control for power transfer and voltage stability in IIG systems driven by ungoverned micro-hydro turbine

This paper introduces a Simplified Perturb and Observe (SP&O) based control aimed at managing the power transfer between a three-phase/single-phase AC load and a regulated DC load, powered by a three-phase Isolated Induction Generator (IIG) connected to an uncontrolled hydro turbine in remote mountainous areas. The controller’s effective operation depends on precise feedback from sensors, which act as input signals. Specifically, two sensors — one measuring voltage and the other measuring current — are used to supply input to the Real-Time Implementation (RTI) platform. The AD202KY voltage sensor is placed at the Point of Common Coupling (PCC) of the IIG, while the LA55-P current sensor measures the AC load current. To improve signal quality and control feedback voltages, additional Signal Conditioning Circuits (SCCs) using op-amp based TL084 and LF353 are connected to the voltage and current sensors, respectively. These SCCs eliminate noise signals and ensure optimal performance. Additionally, we suggest an external excitation scheme for the three-phase IIG, which includes a single capacitor (

scheme) to enable single-phase household supply. The proposed control methodology for power transfer has been successfully tested on two different three-phase, 415 V machines rated at 2.2 kW and 1.5 kW respectively using the dSPACE 1104 as the RTI platform, with a sampling time of 1ms. Importantly, the proposed method shows a reduction in power fluctuations and terminal voltage oscillations in domestic loads during sudden main load applications, underscoring its effectiveness in ensuring smooth power transitions.
