Primary analysis of the loss of Longyangxia power station in abnormal water dispatch

Recently, the abnormal water dispatch from the Yellow River often happens, which abates the drought in downstream as well as bring power loss to LongYangXia power station. The primary analysis of loss reasons and the account methods of the loss are conducted in this paper, which accounts the loss using the methods of correlativity, and provides an example to illustrate how to use the correlativity chart. At last, some advices are proposed such as protecting water and soil, establishing compensation system for abnormal water dispatch and operating the power station optimally.
