摘要
根据天然气流量数学模型,提出了天然气流量信息融合聚类结构,通过ART 2网络和BP网络对影响流量的差压、压力及温度传感器数据进行融合和输出空间聚类分析,制定了在输出流量变化时保持输出压力稳定的聚类控制策略.该系统已用于四川省广元市天然气远程监测调度系统.实测结果表明该系统的天然气流量变化范围在5%～95%时,压力波动不超过±10%.
According to the mathematical model of natural gas flow, a flow control system was proposed based on information fusion and cluster analysis. The system consists of an ART-2 network and a BP network. Pressure differences, pressures and temperatures obtained by sensors are fused and the output spaces are controled according to cluster control strategy. This system has been used in a romote monitering and control system. The operation of the system shows that the pressure fluctuation is controled within 10% when the range of the natural gas flow is between 5% and 95 % of the maximum flow.
