  3. The calculation model of hydro - mechanical transient in existence was deeply studied and the conclusion is that, for kaplan turbine and pelton turbine, neglecting differences of dynamic mater pressure along the turbine spiral case during transient may cause some error in the calculation of pressure rise and speed rise

    本文深入研究分析了軸流式和沖擊式機組過渡過程計算的現有模型，指出現有模型中對蝸殼（進水管）部分的處理方法會給這兩種機組的過渡過程計算帶來相對較大的偏差。
  4. In this paper according to the design scheme of yao heba power station in nan yahe river, the mathematical model with longer and complicated conduit system, elastic water hammer and pid regulating low of voter turbine adjusting system in the case of the small fluctuation has being built, which include conduit system, surge tank, draft tube, water turbine, generator and governor. the hydraulic losses are taken into account, and nonlinearization in water turbine and the governor is also taken into account

    本文根據南椏河姚河壩水電站的設計方案，對水輪機調節系統，按長引水管道復雜引水系統、彈性水擊、調速器為pid調節規律，在小波動情況下，對包括引水道、調壓井、尾水管、水輪機、發電機、調速器在內的水輪機調節系統建立數學模型，並計及引水管道水力摩阻損失，對水輪機、調速器考慮了其中的非線性，利用功能強大的matlab軟體編制了源程序進行計算機模擬計算。
