摘要:
针对已有基于MPPT 的孤岛检测方法存在功率损耗大、存在检测盲区、对电网影响大等不足,提出一种基于MPPT 的分步扰动算法。通过对Boost 升压电路的占空比进行周期性的扰动,实现逆变器输出功率的周期性扰动,在电网断电时影响并网点的电压,使其超出过/欠电压保护阈值,从而检测出孤岛。对已有算法的参数进行了优化,消除了检测盲区。根据电网电压波动的国标,增加了新的判据,减小了检测时间。采取分步扰动算法,减小了功率波动对电网和用电设备的影响。根据IEEE Std. 929—2000 标准并结合国内实际情况,对算法进行了仿真和实验验证,验证了所提算法的有效性。
Abstract:
An islanding detection method by step-by-step disturbance based on MPPT was presented in view of the deficiencies of current islanding detection method based on MPPT,such as the large power loss,non-detection zone,large impact on the grid and so on. This algorithm was based on the periodic perturbation of the duty ratio of Boost circuit to perturb the inverter output power periodically and influence the voltage of public point when the power grid outage to make it exceed the over or under threshold of voltage protection,to detect the islanding. The parameters of the existing algorithms were optimized to eliminate the non-detection zone. A new criterion was added to reduce the detection time according to the national standard of grid voltage fluctuation. In addition,the step-by-step perturbation algorithm was adopted to reduce the impact of power fluctuations on the grid and electrical equipment. Simulations and experiments of the proposed method were carried out according to IEEE Std. 2000-929 and the actual situation.
Eventually,its effectiveness is verified by the results.
