Based On The Research Background And Present Research Status Of Modular Design Method

Hydropower, as a renewable clean energy, is widely used by home and abroad, especially on terms of the small hydropower stations development. A great number of small hydropower stations in china which were built between1960s and1970s and have been running for decades, however, commonly face problems such as unit aging, low efficiency problem and etc. To solve these problems, Chinese government has staged out many relevant documents to guide the process of small hydropower stations technological transformation.Based on the research background and present research status of modular design method, firstly, this dissertation describes the technological transformation process of small hydropower stations sharing system and points out that time-consuming and laborious problems exist in the technological transformation design. To solve these problems, we developed the small hydropower technological innovation sharing system, including system interface development, system database development, data sharing, modular design and a representative reservoir power station in Henan Province is selected as an example as well. Reservoir power station rehabilitation programs were calculated according to the systematical step-by-step guideline. It has been proved that this transformation program is reasonable and reliable. Main conclusions can be drown as follows:1. Based on modular design method, Visual Basic language is used in small hydropower stations technological transformation sharing system. This system is able to complete all the calculations required in the technological transformation design process, and the calculating results are stored in database for modular retrieval.2.This programme uses modular design method which means encapsulating different disciplines of knowledge into different modules and each module just involves only the contents of a discipline, what’s more, needed information and calculated results are stored in overall database and can be shared or called among modulars. This programme mainly contains five parts:the nullah computing module, hydro review module, program comparison and selection module, machine pier Checking of Module and economic evaluation module.3.This programme uses fuzzy analytic hierarchy process (Fuzzy-AHP) to solve turbine selecting problem and scheme comparison problem. Firstly, using the analytic hierarchy process to model and strike the index weight. Secondly, using fuzzy comprehensive evaluation principal to make a comprehensive evaluation and calculates the compressive value of scheme or turbine, therefore, the most optimized plan or model can be determined.Finally, conclusions of this dissertation are summed up and future research direction is pointed out as well.
