V. Core Training Projects: Focusing on Key Industry Skills
The training projects are designed around the core application scenarios of synchronous generators in power systems. Aligned with the skill requirements of industry roles, they ensure a seamless transition between classroom instruction and actual employment. The core training projects consist of two key modules:
1. Synchronous Generator Parallel Operation Training: Enables students to master wiring standards, operating condition debugging, and core principles of load distribution for multiple synchronous generators operating in parallel, while understanding the electrical logic and practical essentials of parallel operation.
2. Synchronous Generator Grid-Connection Training: Simulates the practical scenario of connecting a generator to the power grid. It focuses on developing students' hands-on skills in phase sequence verification, parameter matching, and smooth grid synchronization, aligning with the core operational standards for power system operation and maintenance roles.
