供水管网中压力真实值的批次平差算法

Mean differential algorithm of batches for actual pressure in water supply pipe network system

分析了测压点优化布置的意义及原则,并根据供水周期性,依靠数量有限的测压点压力数据,结合管网的水力计算,利用传统的平差原理,将测压点以外的其它节点压力进行真实性校正,推算出了管网各节点的真实压力值,实现了通过有限测压点数据对管网所有节点压力的全面了解。

This paper discussed the significance and principle of optimal distribution of pressure measuring points and carried out the authentic check for other nodal pressures except pressure measuring points,then calculated the actual pressure dates each nodal in the pipe neework system,based on the periodicity of water supply,relied on the limited pressure data of several pressure measuring points,combined with the hydraulic calculation and used the traditional equal difference theory.It realized the whole nodal pressures to be completely known through limited data of the pressure measuring points.
