摘要:
为解决新疆某团场光伏发电峰谷特性与淡化工艺固定运行模式的供需错配、光伏利用率低等问题，设计基于PLC + 上位机的光伏适配型苦咸水淡化控制系统。系统以PLC为控制核心，增设缓冲水箱实现工艺与能量双解耦，结合环境参数构建光伏峰谷动态识别模型。通过引入卡尔曼滤波、变参数PID控制等算法，实现光伏峰谷精准识别与工艺参数精准调控。试验验证表明，系统光伏峰谷识别响应时间?1s，识别准确率?98.5%，工艺参数控制精度达液位±0.04m、流量±0.09m?/h、压力±0.015MPa，光伏利用率提升至85.6%，可在高温、高沙尘工况下实现24h连续稳定供水，为西北偏远地区全光伏供电水处理工程提供智能化控制方案。
Abstract:
To address issues such as the mismatch between the peak - valley characteristics of photovoltaic power generation and the fixed operation mode of desalination process in a certain farm in Xinjiang, as well as low photovoltaic utilization rate, a photovoltaic - adaptive brackish water desalination control system based on PLC + supervisory computer was designed. The system uses PLC as the control core and incorporates a buffer water tank to achieve dual decoupling of process and energy. It combines environmental parameters to construct a dynamic identification model for photovoltaic peak - valley and formulates a refined linkage control strategy. By introducing algorithms such as Kalman filtering and variable parameter PID control, it achieves precise identification of photovoltaic peak and valley. Experimental validation shows that the system’s response time for photovoltaic peak and valley identification is ? 1 s, with an identification accuracy of ? 98.5%. The control precision of process parameters reaches a liquid level of ± 0.04 m, flow rate of ± 0.09 m?/h, and pressure of ± 0.015 MPa, while the utilization rate of photovoltaic energy is improved to 85.6%. This system can provide continuous and stable water supply for 24 hours, offering an intelligent control solution for water treatment projects powered entirely by photovoltaic energy in the remote areas of Northwest China.
