摘　　要：在配电网的电压和灵敏度的分析上,介入分布式电源会对配电网的安全性能造成一定的影响。回路分析法可以得到配电网中运行参数的动态变化。在具体的实践工作中,需要通过回路分析法,转变配电网中电路的方式,随后介入分布式电源后结合电压波动理论对效果进行研究,其中还会涉及到叠加定理,对回路中的指路电流进行叠加。配电网介入了分布式电源,电源系统会出现转变,不再是单一的电源,而是作为多种电源系统而存在。建设节点电压需要使用到回支关联矩阵,对线路损耗中的灵敏度分析电压产生的变化。最后在IEEE33节点当中对配电网进行仿真的研究。In the analysis of voltage and sensitivity of distribution network,the involvement of distributed generation will have a certain impact on the safety performance of distribution network.The dynamic changes of operating parameters in distribution network can be obtained by loop analysis method.In the specific practical work,we need to change the way of the circuit in the distribution network through the loop analysis method,and then study the effect after intervening in the distributed generation combined with the voltage fluctuation theory,which also involves the superposition theorem to stack the guiding current in the loop.When the distribution network is involved in distributed generation,the power system will change.It is no longer a single power supply,but exists as a variety of power systems.The construction of node voltage needs to use the back branch incidence matrix to analyze the change of voltage in the sensitivity of line loss.Finally,the distribution network is simulated in ieee33 node.
