摘要
针对坝式水电站水位大落差的问题,设计了一种能自适应水位的浮标装置及其控制系统。装置主要由浮标主体、电源系统、智能控制系统、驱动系统及附件等模块组成,通过竖直角度控制算法和沉浸高度控制算法实现锚链长度的自动调节。为保证沉浸高度测量的可靠性,设计基于扩展卡尔曼滤波器的状态估计算法。该装置应用于水位大落差的坝式水电站,可对通行船只提供警示功能。
Aiming at the problem of large water-level drop for a dam-type hydropower station,a buoy device and its adaptive control system were designed.The device mainly consists of the buoy body,power supply system,intelligent control system,drive system and their accessories.Through making use of a vertical angle control algorithm and an immersion height control algorithm,the auto-adjustment of the anchor chain was achieved.For purpose of ensuring the reliability of immersion height measurement,an extended Kalman filter-based state estimation algorithm was designed.The device developed can be applied to alert ships passing by the dam-type hydropower station with the water level dropped sharply.
