水机效率试验与经济效益

Test of Turbine Efficiency and Economic Benefit

根据我国水电厂管理的现状，论述了水轮机效率没有被充分利用，忽视经济效益的观点。一方面是检修管理没有与水轮机效率产生的效益相结合；另一方面众多的老机组效率低下，这些老机组可以在投入不多的条件下取得提高效率（约５％）的效益。本文介绍了五种适合于现场应用的水机效率试验方法；推荐了一组针对检修管理的数学模型。

In light of the administrative situation within the electric Power plants in China, some unhealthy tendencies (such as turbine efficiency is not made use of ,economic benefit is neglected) are stated in this paper. Search to the bottom, one hand is that the administrative inspection and repair does not combine with the benefit which will be produced by turbine efficiency; on the other hand, numerious old units are in the state of low efficiency but can raise their efficiency at 5% or so under the conditions of low investment.
