The sub-events are in a sequential relationship; the cooling equipment operation can be divided into lower-level events such as cooler operation and electric valve operation, and the cooling equipment operation is the parent event; the event relationship diagram is a graphical representation method that can clearly show the relationship between events; S303, establishing a computational model: According to the event relationship diagram, a corresponding operation model is established; the operation model includes a mathematical model and a computer model, which is used to calculate and predict the operating status of the hydropower station unit; Taking the startup event as an example, during the startup event, when the governor startup sub-event is completed and the speed is greater than 5%, the unit operation state model calculation is triggered, the unit operation state time interval is recorded, and the key unit status data is interrupted and audited in real time; when the grid-connected operation sub-time is completed, and the unit speed is greater than 95%, and the active power is greater than 5MW, the unit grid-connected interval model and steady-state interval model calculation are triggered.

In the event relationship model of hydropower station units, the hydropower system is decomposed into multiple subsystems according to the characteristics and spatial distribution pattern of the hydropower station, and scheduling and coordination optimization are carried out area by area. The cyclic scheduling algorithm is used as the task scheduling algorithm to assign all subtasks to all processors in a certain order. After each processor completes a subtask, it takes out a new subtask from the remaining subtasks for processing. S404, Synchronization and Communication: Data exchange and task synchronization are performed between multiple processors or computing nodes, so that all processors or computing nodes can correctly complete the assigned tasks; in the event relationship model of the hydropower station unit, the neighborhood information is updated for each spatial subdomain before each calculation; the message passing interface MPI is used for synchronization and communication, and each processor establishes a message sending and receiving channel with other processors to perform data exchange and task synchronization between processors; S405, parallel computing optimization: Perform algorithm optimization, data structure optimization, parallel algorithm optimization and hardware optimization on the parallel computing process; in the event relationship model of the hydropower station unit, parallel computing optimization is performed by applying the large system decomposition and coordination method and multi-core cluster parallel computing; S406, performance evaluation: The performance of parallel computing is evaluated through actual operation data to determine the effect of parallel computing. In the event relationship model of the hydropower station unit, the number of floating-point operations FLOPS is used to evaluate the performance of parallel computing.
