摘要

本文对跨流式水轮机和同步发电机(SG)特性在超低水头水力发电中的适用性进行了分析。前者是选定涡轮机制造商的商业产品，而SG是从公开市场购买的新商业产品。根据汽轮机的技术指标:最小功率为10kw，转速为300rpm，转轮外径(Do)为0.3 m，传动比为1:5，试验验证了其与发电机耦合时的适用性。结果表明，发电机的性能不如预期。发现电压波纹和电流波相当高。当发电机负荷发生变化时，v形带会产生振动。发电机的效率约为60.61%。该结果有望成为测试涡轮和发电机耦合时的适用性的技术程序;不管它们是新产品还是现有产品。

Suitability Analysis of Cross-Flow Turbine and Synchronous Generator Characteristics for Very Low Head Hydro Power Application

In this paper, suitability analysis of cross-flow turbine and synchronous generator (SG) characteristics for very low head hydro power application is performed. The former is a commercial product from a selected turbine manufacturer while the SG is a new commercial product bought from the public market. Given the technical specifications of the turbine: minimum power is 10 kW, rotation is 300 rpm, outer diameter (Do) of runner is 0.3 m, the transmission ratio is 1: 5, its suitability when coupled with a generator was tested experimentally. The results show that the generator performance was not as expected. Voltage ripples and current waves were found to be quite high. Vibrations always occur on the V-belt when the load of generator is changed. The efficiency of the generator was found to be around 60.61%. The results are expected to become a technical procedure in testing the suitability between a turbine and a generator when they are coupled; regardless they are new products or the existing ones.
