Problems solved by technology

[0002] At present, among the teaching aids related to power system experimental equipment widely used in higher education systems, the most advanced and representative one is the power system experimental platform developed by Wuhan Huada Electric Power Automatic Technology Co., Ltd. , excitation control, generator speed regulation and other teaching experiments, and provide a variety of adjustment and control methods, such as manual automatic quasi-synchronization, semi-automatic quasi-synchronization and full-automatic quasi-synchronization for the synchronous control mode, constant UF mode for the excitation control mode , constant IL method, constant u method and constant Q method, but the research and development of this product has a history of more than ten years. Although various control methods are used, it is impossible to observe and measure each link, limited by the original technology Level, the core control chip uses a single-chip microcomputer, its computing speed and comprehensive performance can no longer meet the realization of many complex control algorithms today, and each test bench is an isolated single platform, which cannot be connected with substations and power supply and distribution devices to become a real on-site Large-scale interconnected power systems cannot provide a more realistic and complex power system network

However, domestic leading industrial power equipment manufacturers such as Henan Xuji simply use products from industrial sites when designing power system experimental teaching aids, without combining the characteristics of teaching, and can only be used for demonstrations. Teachers and students can complete on the equipment. Work is very limited and doesn't really meet the teaching requirements
