In order to resolve the question, in the thesis a simulation arithmetic of hydro - electrical system is put up. the equations of hydro - electrical system are divided to two parts, one of which consists of the differential equations of conduit system, hydro turbine and generator ' s rotator and is solved by characteristic equation arithmetic, the other of which consists of the differential equations of generator, magnetic system and grid and is solved by longge - kuta arithmetic or covert integrated arithmetic. through the alternative solving of the two parts, the simulation results of the large - disturbance transient could be abstained eventually
為解決這一問題,本文提出了一種將水力系統和電力系統方程交替求解的水電系統聯合模擬演算法,即將包括輸水系統、水輪機以及機組轉子等部分的水力系統差分方程作為一部分,將包括同步發電機、勵磁系統以及電網等部分的電力系統微分方程或差分方程作為另一鄭州大學工學碩士論文部分,對前一部分採用特徵線法求解,對后一部分根據模型形式採用龍格一庫塔法或隱式積分法等演算法求解,這兩部分的求解過程交替進行,最終即可得到水電系統大擾動過程的模擬結果。Applied the precise integration method to solve stiff equations and nonlinear equations, and improved the method from explicit and implicit aspects. it found that the exact solution of some differential equations may be obtained, and always stable absolutely
