基于非线性动力学建模的PTSC滤波与无功补偿系统研究
|
摘要
根据煤矿集团变电站供电模式的不同,可知大功率直流设备与变频设备的使用均存在无功和谐波问题的影响,极易使电网运行质量受到干扰,使煤矿开采存在风险。而为了解决以上问题,必须基于非线性动力学建模系统明确无功与谐波影响的确切位置与参数,落实模拟实验,而后再提供对应的滤波装置与无功补偿系统,分辨是否能够遏制此类问题继续出现,才能使此类变电站问题得以有效解决。
According to the different power supply modes of substation in a coal mine group, it is known that the use of highpower DC equipment and frequency conversion equipment have the influence of reactive power and harmonic problems, which can easily interfere with the operation quality of power grid and bring risk to coal mining. In order to solve the above problems, the exact position and parameters of reactive power and harmonic influence must be defined based on the nonlinear dynamic modeling system, the simulation experiment must be carried out, and then the corresponding filtering device and reactive power compensation system must be provided to distinguish whether this kind of problem can be contained or not, so that the problem of this kind of substation can be solved effectively.
