多热源环状热网故障关阀方案及程序实现

VALVE CLOSING SCHEME AND PROGRAM COMPILATION FOR MULTI–HEAT SOURCE RING–SHAPED HEAT SUPPLY NETWORK IN MALFUNCTION

针对多热源环状热网故障关阀的非对称性,提出了一种基于图论的空间热网关阀方案。当环线上发生故障时,只关闭故障点所在的供水管或回水管上的阀门。采用面向对象的程序设计思想,编制了关阀和故障影响分析程序,并应用于实践。结果表明,该关阀方案及算法可适用于各种型式的热网,有效提高故障抢修的效率和科学性。

Considering the asymmetry of valve closing of multi-heat source ring-shaped heat supply network in malfunction, a kind of graph theory-based space heat supply network valve closing scheme is put forward to only close the valve on water supply pipe or return pipe where the malfunction points exist when malfunction happens on the ring-shaped supply network.Object-oriented programming concept is adopted to program the processes for valve closing and failure effect analysis and then apply them in practical cases. Application practice proves that this valve closing scheme and algorithm are applicable to various heat supply networks and could effectively improve the efficiency and scientific level of malfunction repair.
