Abstract

At present, China’s hydropower industry has entered a new stage of high-quality development. In this paper we made a review on the technical status in two professional fields, namely, turbine governor and synchronous motor excitation. We introduced the progresses made in control theory research and regulation mode of special turbine, and expounded the main technical characteristics of dual-core excitation regulator. Moreover, we summarized the major achievements of Changjiang (Yangtze) River Scientific Research Institute in technology innovation, product innovation and industry standard formulation for hydropower unit control equipment in the past decade, and looked into the prospect of hydroturbine governor and synchronous motor excitation technology to make greater contribution to carbon peak and carbon neutrality goals. Hydroturbine governor and synchronous motor excitation should be autonomous and controllable, and must be improved in terms of reliability and intelligence.

Key words

turbine governor / synchronous motor excitation / controller / electro-hydraulic converter / electrical power bridge / grid related tests / smart grid
