摘　　要：介绍了一种铅酸蓄电池的三阶动态等效模型,通过电池放电试验对等效模型中的容量、主支路以及热量模型参数进行计算,并基于PSCAD/EMTDC仿真平台搭建了适合直流配电网的铅酸蓄电池三阶动态模型和储能单元接入直流配电网的并网模型。通过搭建的储能单元接入直流配电网的试验平台,试验结果验证了所构建的并网模型的有效性和可行性。Introduction was made to the third order dynamic equivalent model for a kind of lead-acid storage battery. the parameters of capacity, main circuit branch and thermal model were calculated by the battery discharge test, and based on the PSCAD/EMTDC simulation platform, the third order dynamic model for the lead-acid storage battery suitable for the direct current （DC） distribution network was built, as well as the grid connected model of the energy storage unit connected to the DC distribution network. The experimental platform of the energy storage unit connected to the DC distribution network was set up. The test results verify the effectiveness and feasibility of the con-structed grid connected model.
