沼气发电机并网一次主接线及继电保护配置的探讨

Discussion on the Connection of Methane Alternator Parallel in Main Power Grid and the Relay Protection Configuration

如何利用污水处理产生的沼气，一直是环保节能的重要课题；而将沼气能源转换成电能则是实现能零再利用的最佳方式。由于污水处理产生的沼气呈季节性变化，因此，沼气发电机并网的接线方式及保护配置就有其特殊性，本文针对该问题进行了详细的阐述。

How to utilize methane generated from wastewater treatment has been an important task of environment protection and energy saving. The optimum approach to implementing energy reuse is to transform power from methane into electricity energy. Due to the seasonal change of methane generated from wastewater treatment, the connection of methane alternator into the grid and its protection configuration vary accordingly. The article aims to focus on a comprehensive discussion on this topic.
