摘要
在静态范围内利用三元分析法阐述了OLTC动作引起的Pmax-、Vcr-曲线的变化,研究了在接入分散,电源的电力系统中,OLTC变比调整对其静态电压稳定极限的影响,并采用两机系统进行了仿真分析得出,OLTC变比变化改变了系统的最大传输功率稳定极限Pmax和临界电压稳定极限Vcr,影响了电力系统稳定运行范围;由于分散电源在配电网的接入,OLTC变比变化对Pmax和Vcr的影响程度不同。
This article studies the changes of the Pmax-Ф,Vcr-Ф curves corresponding to OLTC adjustment within the static scope by using the ternary analytical method, and states the influence of OLTC transformer ratio change on static voltage stability limit of power system connected DG, and it carries on the simulated analysis of the 2-machine system in this paper. Such conclusions have been drawn as followings.. OLTC transformer ratio adjustment changes the maximum transmission power and critical voltage of the power system, and effects the Stable operating range of power system, OLTC transformer ratio change effects the degree of influence on the Pmax and Vcr-Ф differently due to distribution systems connected DG.
