风力发电非并网系统的模型试验

为解决风电在电网中的贡献率难以超过10%的世界性难题,针对风的高度不稳定性导致风电大幅度波动这个原因,提出发展非并网风电的新思路,即大规模风电不并入电网,直接应用于一系列能适应风电特性的终端用户.通过模型试验对非并网风电直接应用于氯碱和电解铝生产的可行性进行研究.试验结果表明,氯碱和铝电解生产均能较好地适应风电特性,生产过程中的电压或电流波动,只影响产品的产量,不影响产品的质量和工艺流程;双路供电时,网电自动为风电补充,保证了电解槽的稳定生产.利用非并网风电进行大规模工业化生产具有很大可行性.

Model experiment on large-scale non-grid-connected wind power system

In order to resolve the universal problem that the contribution rate of wind power to electricity net was lower than 10%,because of the high degree of instability in wind energy which seriously restricts wind power application,a new approach to develop the non-grid-connected wind power is proposed.In the new approach,the large-scale wind power is not connected into the power grid but is directly applied to a series of end-users which are suitable for the characteristic of wind power.The feasibility of non-g...
