水电厂辅助设备计算机仿真研究(I)

Simulation for the auxiliary equipment of hydropower plant (Ⅰ)

结合浙江省新安江水力发电厂,对水电厂辅助设备仿真进行了研究.建立了油、水、气系统数学模型和仿真模型.将油系统分为油槽油位、压油槽及工作门等子系统进行仿真;将气系统分为制动用气、调相压水用气、压油槽补气等子系统进行仿真;对水系统建立整体模型,根据水系统的流体网络图形,得出一种流体回路计算方法.该模型较好地解决了水电厂辅助设备计算机仿真问题.

Auxiliary equipment simulation for the Xin'anjiang Hydropower Plant is presented. Mathematical and simulation models for oil, water and compressed air systems were developed based on simulation studies. The pressure oil system of the plant was divided into subsystems of oil level, pressure tank and service gates; the compressed air system was divided into braking subsystem, compensating subsystem and the subsystem of air replenishing for air,oil pressure tank. The method of fluid circuit calculation was available according to the fluid network of water system. The model could successfully solve the simulation problems of the auxiliary equipment for hydropower stations.
