摘　　要：热力网络是多能源系统的重要组成部分。电网和热网建模机理和时间尺度存在较大差异,传统电力系统暂态仿真程序难以直接应用于电-热多能源系统动态仿真。根据电-热类比方法,采用基本电气元件构建了热力管道热路和水路等效电路模型。同时,基于查表法构建了计及设备运行特性的空气源热泵等效电路模型。为提高仿真效率,进一步提出了基于电磁-机电暂态建模框架的电-热多能源系统动态仿真方法。电网采用机电暂态建模,热网采用电磁暂态建模,空气源热泵模型作为接口模型,完成电网模型和热网模型之间的数据交互。电网模型与热网模型均采用毫秒级及以上仿真步长,实现了高效的多能源系统动态仿真。最后通过算例分析验证了所提模型和仿真方法的有效性。Thermal network is an important component of multi-energy system.There are significant differences in modeling methods between electric network and heating network.It is difficult to directly apply traditional power system transients simulation program to modeling of multi-energy system.With the help of electrical-thermal analogy,the dynamic models of thermal circuit and hydraulic circuit of pipe represented using circuit equivalents.At the same time,the equivalent circuit model of the air source heat pump considering the operating characteristics of the equipment is constructed based on the table lookup method.In order to improve the simulation efficiency,a new method for modeling and simulation of electric and heating multi-energy systems are proposed based on electromagnetic and electromechanical transient simulation technique.The electric network is simulated in electromagnetic transients program.the heating network which is modeled with basic circuit elements is simulated in electromechanical transients program.The air source heat pump which connects the electric and heating networks is used as interface model.The multi-energy system model is capable of using a large time step of size to maintain high simulation efficiency.Diverse tests are carried out to validate the proposed models.
