摘要
利用遗传算法求解由连续性方程和能量方程组成的供水管网阻力系数辨识方程组,可以得到有一定可信度的辨识方程组的解,该解可以作为管网阻力系数的辨识结果。利用该辨识方法对实际算例进行计算,所得辨识结果证明了基于遗传算法的供水管网阻力系数辨识方法的实用性和合理性。该方法也可以应用于其他管网阻力系数辨识,如供热管网等。
The identification equations of pipe resistance coefficients in water distribution system composed by continuity equation and energy equation were solved by genetic algorithm （GA）. The solution of identification equations with certain credibility could be considered as the identification results of pipe resistance coefficients. The identification method was used to calculate the actual example, and the results proved the practicability and rationality of the identification method of pipe resistance coefficients in water distribution system based on GA. This method can also be applied to identification of resistance coefficients of other pipe networks, such as a heating pipe network.
