代码说明:

说明:  为建立供热管网的在线优化运圩、故障实时诊薪 及赏真分析和培训呆缆,必须建立一种高精度的蒸巍供热管 习动恋仿真模型。该模型将蒸汽处理成为单相可压缩洗件, 将营罔处理成为由节点南支路组成的一种网络结构。在仿真 计算中,采用隐式Euler算法、线性迭代方法和稀疏矩畦算 法隶解由物理模型所得的非线性擞分方程组。证明7|:角的 算法具有大范围收敛特性。此方法祷被应 于青岛百蒸汽供 热管网的工程项目中。(Steam heating network of dynamic simulation modeling)

  • Grid-Connected-PV-Array
    Two demos illustrate use of SimPowerSystems for modeling a PV array connected to a utility grid. PVarray_Grid_IncCondReg_det.mdl is a detailed model of a 100-kW array connected to a 25-kV grid via a DC-DC boost converter and a three-phase three-level Voltage Source Converter (VSC). Maximum Power Point Tracking (MPPT) is implemented in the boost converter by means of a Simulink model using the “Incremental Conductance + Integral Regulator” technique. PVarray_Grid_PandO_avg.mdl is an average model of a 200-kW array connected to a 25-kV grid via two DC-DC boost converters and a single three-phase VSC. The MPPT controller based on the “Perturb and Observe” technique is implemented by means of a MATLAB Function block that generates embeddable C code.
