A hydropower generating unit needs both a turbine governor and an excitation system. Both respond to measurements and adjust the unit’s behavior, but they act on different parts of the energy conversion process. The governor controls the turbine’s mechanical input. The excitation system controls the generator’s magnetic field. Understanding this distinction helps explain how a…
Switching off an excitation power supply does not make a generator’s magnetic field disappear immediately. The rotor field winding stores magnetic energy, and that energy must be released as the field current decreases. This is why de-excitation is an important part of synchronous generator operation. Understanding the process explains what happens after an excitation shutdown…
Excitation control plays an essential role in the operation of a synchronous hydropower generator. By controlling the electrical energy supplied to the rotor field, the excitation system supports generator voltage regulation and reactive power control. Understanding its operating modes helps plant owners and engineers evaluate equipment specifications and define retrofit requirements. Two terms frequently appear…
A hydropower plant depends on more than the turbine governor and excitation system. Its daily operation also involves gate equipment, hydraulic pressure units, compressed-air systems, drainage pumps, HVAC equipment, water filters, and other auxiliary devices. These systems have different control requirements, but they must work within the same plant operating environment. A suitable automation and…
On August 12, NSD Electrical hosted a public-interest vocal wellness workshop for female employees at the company’s headquarters. The event aimed to support women’s physical and emotional well-being while helping them manage the pressures of work and daily life. The workshop was held under the guidance of the Hongshan District Women’s Federation and jointly organized…
On the morning of the 8th, the National Science and Technology Awards Conference, the Academicians Conference of the Chinese Academy of Sciences and the Chinese Academy of Engineering, and the 11th National Congress of the China Association for Science and Technology were held in Beijing. President Xi Jinping presented awards to the recipients of the…
This summer, electrical engineering students from the School of Automation at Wuhan University of Technology visited NSD Electric’s Hanyang manufacturing base for the company’s 2026 industrial internship program. As an important practical training base that has maintained close cooperation with the university for many years, NSD Electric is committed to supporting engineering education through real-world…
The 2026 China Smart Energy Conference successfully concluded on July 11 at the Chengdu Century City New International Convention and Exhibition Center. The event brought together energy representatives from more than 40 countries, leaders of international organizations, experts, scholars, and industry professionals to discuss emerging trends in smart energy and promote digital transformation and high-quality…
The world’s highest rated-head pumped storage power station and China’s largest single-unit capacity pumped storage project has officially entered full commercial operation. On June 25, 2026, following the successful completion of a 15-day assessment trial operation of the final generating unit, the Zhejiang Tiantai Pumped Storage Power Station officially achieved full commissioning and started commercial…
