尽人皆知,对一个工业过程设备来说,搞好能源控制和管理会节省很多资金。对大多数过程动力设备,即使所用的控制仪表很简单,凭着操作人员的技艺,也能有效地操纵设备的各个单元(锅炉和透平发电机等)。然而,设备的各个单元效率究竟如何并不得而知。而且,把若干单元并联起来构成一个总能源的话,其中哪个单元最有效,各单元的负载怎样组合才能以最低的成本提供能源等问题都是不清楚的。为了回答上述问题,必须依靠计算机的 It is well known that for an industrial process plant, a great deal of capital savings can be achieved by improving energy control and management. For most process power equipment, even with the very simple control instrumentation used, the operator’s skills make it possible to efficiently operate the various elements of the plant (boilers and turbine generators, etc.). However, it is unclear exactly how efficient the various elements of the equipment are. Moreover, it is unclear which of these units should be the most efficient when paralleled together to form a single source of energy, how combinations of units’ loads can be combined to provide energy at the lowest cost. In order to answer the above questions, we must rely on the computer
