The world's largest new energy distributed tuning camera group artificial short-circuit disturbance test was completed

Xining, China News Agency, December 12 (Li Jiangning, Chang Bingyu, Lu Guoqiang) China State Grid Qinghai Electric Power Company released on the 12th, on the 11th, the world's largest new energy distributed modulator group artificial short-circuit disturbance test was successfully completed, this test is the first test in the northwest high-proportion new energy grid system characteristic verification series of tests specifically for the new energy distributed machine group new technology equipment. The standardized transformation of new energy network-related parameters and the reactive dynamic adjustment characteristics of distributed modulator groups in large-scale new energy bases are further verified.

Previously, on November 8, at the 10-million-kilowatt new energy base in Hainan, Qinghai, the first batch of 11 new energy distributed tuning cameras were put into use, and the world's largest group of new energy distributed modulators was officially formed. According to Wang Dongyang, commander-in-chief of the test site, the test was carried out under the three modes of distributed tuning camera not put into operation, distributed tuning camera zero power operation, and distributed tuning camera maximum incoming phase and maximum stagnation phase operation. The test covered a variety of new energy equipment, and the on-site measurement point reached 14.

"Through the artificial short-circuit test under three modes, the most typical single-phase grounded short-circuit fault in the operation of the power grid is simulated, which comprehensively verifies the response characteristics of the new energy cluster and the adjustment ability of the distributed regulator in the steady-state and transient state, and accumulates valuable experience for the construction of a new power system mainly based on new energy." Fang Baomin, director of the State Grid Qinghai Electric Power Regulation center, said.

It is reported that Qinghai Power Grid is currently the provincial power grid with the highest proportion of new energy installed capacity in the country. The scale of new energy is constantly expanding, and the safety problems of the "large DC" and "high proportion of new energy" power systems are prominent. In order to transport clean energy on a larger scale and in a wider range and accelerate the clean energy transformation in Qinghai, the State Grid Qinghai Electric Power Company proposed the new energy transient performance evaluation method and transformation mechanism of the "double high" power system, established a model of "new energy distributed tuning camera + new energy cluster network management", significantly improved the active support capacity of qinghai Hainan 10 million kilowatt new energy base, and greatly improved the ± 800 kV Qingyu UHVDC transmission capacity and regional new energy consumption.
