Abstract
The paper takes Jinping II Hydropower Station (8 × 600MW) as an example based on the internal mechanism and operating characteristics of the system, the complete simulation model of the super-long and large water diversion and power generation system has been completed finally.Besides, the method of parameter calibration and correction for the main elements of the system is proposed.By the simulation model, two typical hydraulic transient process test conditions are simulated, here the involved test conditions are as following: double load rejection and primary frequency regulation.At the same time, the calculated results are compared with the test results. The results show that the proposed simulation model can describe the dynamic response characteristic of the super-long and large water diversion and power generation system accurately.
Highlights
A hydraulic transition process is the process in which water flow is changed from one stable state to another by some disturbance [1]
As the total installed capacity, single unit capacity and flow of JP II Hydropower Station are large, and its super-long and large-diameter hydraulic tunnel, giant differential surge tank and large hydrogenerator units are characterized by extremely complex hydraulic conditions, it is one of the key technical problems restricting the construction of JP II Hydropower
This paper takes JP II Hydropower Station as the research object, and uses the user-defined modelling function provided by HYSIM software which is a simulation calculation software for complex system hydraulic transition process, to establish a complete hydraulic transition process simulation model for superlong and large water diversion and power generation system
