摘要: |
针对配电网中存在谐波、无功以及负荷频繁波动等问题,提出了含混合储能(HESS)的三相四线制配电网静止同步补偿器(D-STATCOM),实现配电网无功补偿和谐波抑制,平抑负荷有功功率波动。首先,针对三相四线制配电网,通过对传统ip- iq谐波电流检测法改进,实现了对负荷所需的有功、无功和谐波补偿电流的准确检测。在此基础上,将超级电容器和铅酸蓄电池组成的混合储能系统引入到补偿装置中,实现了对配电网有功、无功和谐波电流的全补偿。结合不同储能装置的充放电特性,采用协调控制方法,确保系统对配电网能量的迅速准确补偿。最后结合某建筑配电网实际负荷,验证了三相四线制D-STATCOM/HESS系统及其控制算法在谐波抑制、无功补偿和平滑负荷有功波动方面的有效性。 |

Abstract: |
Three phase four wire D-STATCOM system with HESS (D-STATCOM/HESS) is proposed to deal with the harmonic, reactive power, and load frequent fluctuation in distribution network to realize distribution network reactive power compensation and harmonic suppression and smooth load active power frequency fluctuation. Firstly, the traditional harmonic current detection method of ip- iq is improved to achieve an accurate detection of active and reactive power and harmonic compensation current on load. Secondly, due to the charge and discharge characteristics of lead-acid batteries and supercapacitors, coordination control method is employed to ensure distribution network energy compensated quickly and accurately. Finally, the three-phase four-wire D-STATCOM/HESS system and control algorithm are verified by the actual civil load distribution network circuit simulation. The system designed is shown effective in suppressing harmonics, reactive power compensation and smoothing fluctuations of the active power.
