中文摘要:

介绍了电气化铁路对于风电场运行的影响。针对运用广泛的交直传动型电力机车进行说明,介绍了典型交直传动型机车的接线方式及其结构特点。选取使用三相V/v接线方式的牵引变电站进行研究,分析了其产生三相不平衡的机理以及其接入电网后带给风电接入点的电能质量问题。在交直型机车接入风电并网点的背景下,研究了直驱风电机组在三相不平衡条件下产生直流侧二倍频波动的机理,提出了一种以稳定直流侧电压为目的正负序双电流控制策略。最后,在PSCAD中,对交直型机车与直驱风电场进行建模并接入桂林电网,验证该类电气化铁路给风电场带来的电能质量问题,仿真直驱型风电机组在三相不平衡条件下利用正负序双电流控制策略的运行情况。

英文摘要:

The impact of railway to wind farm is introduced. An introduction about the AC/DC electric locomotive which is used widely and its tractive power supply system is made,and its wiring and structural features are introduced. The typical traction substation which uses three phase V/v connected traction transformer is chose to be studied. After that, the generation of the three-phase imbalance and the power quality problems of wind farm caused by the AC/DC electrified railway are studied. The principle of the generation of second harmonic fluctuation in direct driven turbine DC side,and a positive and negative sequence dual current control strategy is presented for direct driven wind turbine under the circumstance that the AC/DC electric locomotive is connected to wind farm. At last, the model of AC/DC electric locomotive and direct driven wind farm are established, and the power quality problems of wind farm caused by the AC/DC electrified railway is validated, also the running situation of direct driven wind turbine with positive and negative sequence dual current control strategy under three-phase imbalance is simulated.
