摘要
企业配电网直接服务企业生产,其供电质量和供电可靠性对企业意义重大,针对企业负荷构成的特殊情况,研究了符合企业实际情况的负荷数学模型,应用切实可行的无功补偿措施改善了企业配电网无功分布情况,对提高企业电能质量以及经济效益都有重要意义。
Enterprise distribution power system serves directly to manufacture,and the energy quality and power supply reliability are important to the development of enterprises.In view of the component of enterprise load,the study on the establishment of load model and improve the situation of energy-saving have important theoretical and practical value.The static load model,the dynamic load model,the assembly induction motors equivalent model was compared in the paper from identification,precision,etc.In view of the fact that induction motors are the main element of enterprise load,assembly induction motors load model is up to the fact of enterprise.On the basis of the of above study production,back/forward sweep method for radial distribution load flow was used to analyse the operating conditions of enterprise in the paper.The load model and the compensation algorithm have been tested.The results indicate that they are effective in the analyze and calculation of enterprise distribution power system.
