Recently, a 50 Mvar exciter with air-cooling technology, developed by Dongfang Electric Corporation under the Dongfang Electric Group, and designed for use on the power side of wind farms, was put into operation in Xing’an League under China General Nuclear Power Group. It performed excellently in terms of various parameters such as dynamic characteristics, vibration levels, temperature rise, and noise levels; in fact, its loss values and vibration levels were far below the requirements specified by national standards and the contract. The maximum shaft vibration level was only 14 microns.
Compared to large synchronous condensers installed on the traditional grid side, distributed synchronous condensers operating at the power source side offer advantages such as higher integration levels, better system stability, shorter construction times, and superior regulation performance; they also exhibit improved transient, sub-transient, and steady-state performance. CGN Xing’an League synchronous condenser is also the first 50 Mvar-class GVPI excitationless synchronous condenser in China to use air-to-air cooling; it incorporates an innovative variable-frequency air-to-air cooler that can automatically adjust losses based on operating conditions and ambient temperature, thereby significantly reducing the operational losses of the synchronous condenser. Inner Mongolia boasts exceptional resources in solar and wind energy, ranking among the top in the country in terms of new energy generation. Dongfang Electric supplied all 2 sets of 50 Mvar shunt-air-cooled condensers for the wind farm in Xingan League, Inner Mongolia. Once the two frequency regulators are put into operation, they will significantly enhance the capacity for transmitting new energy from the Mengdong region, thereby contributing to the economic development of the revolutionary old areas in Xingan League.

Compared to large synchronous condensers installed on the traditional grid side, distributed synchronous condensers operating at the power source side offer advantages such as higher integration levels, better system stability, shorter construction times, and superior regulation performance; they also exhibit improved transient, sub-transient, and steady-state performance. CGN Xing’an League synchronous condenser is also the first 50 Mvar-class GVPI excitationless synchronous condenser in China to use air-to-air cooling; it incorporates an innovative variable-frequency air-to-air cooler that can automatically adjust losses based on operating conditions and ambient temperature, thereby significantly reducing the operational losses of the synchronous condenser.
Recently, the first domestic distributed 50 MWe GVPI air-cooled condenser, independently developed by the Generator Factory of Shanghai Electric Power Station Equipment Co., Ltd., completed a 168-hour trial operation at the Daiyang Gathering Station and was officially put into commercial operation. The distributed 50 MW class air-cooled synchronous condensers represent China’s first attempt at applying such technology in the field of new energy power generation, with the aim of addressing the issue of transient overvoltages caused by a high proportion of new energy sources. It possesses excellent transient and steady-state performance as well as reactive power regulation capabilities; it can also increase the system’s short-circuit capacity and short-circuit ratio, thereby enabling the large-scale transmission of renewable energy power and ensuring the safe and stable operation of the power grid. The 5 distributed 50 MWe GVPI air-cooled condensers in this project represent the first application of Shanghai Electric’s condenser products in the field of new energy power generation. Currently, the remaining 4 units are also working towards achieving the “168” milestone, with completion expected before the Spring Festival.
At 11:38 on September 13, 2021, the first 50Mvar distributed salient-pole synchronous condenser developed in China by Dongfang Electric Co., Ltd. of Dongfang Electric Group (hereinafter referred to as “Dongfang Electric”) was successfully connected to the primary side of the 330 kV Xiayang substation in the Hainan New Energy Base in Qinghai and put into operation. During the unit’s connection to the grid and after it went into operation, various parameters such as tile vibration, tile temperature, and noise were excellent, earning high praise from the owner and maintenance personnel.
