"5, 4, 3, 2, 1, perform operations..." On December 11, at the site of the 10-million-kilowatt new energy base in Hainan Tibetan Autonomous Prefecture, as an arc of light broke through the sky, the artificial short-circuit disturbance test of the world's largest new energy distributed modulator group was successfully completed. The success of the test further verifies the standardized transformation of new energy network-related parameters of large-scale new energy bases and the reactive dynamic regulation characteristics of distributed modulator groups, which is of great significance for the safe and stable operation of Qinghai power grid and the promotion of intensive development and large-scale delivery of new energy in Qinghai.
On November 8, in the Hainan 10 million kilowatt new energy base, the first batch of 11 new energy distributed tuning cameras were put into use, and the world's largest new energy distributed tuning camera group was officially formed. The artificial short-circuit disturbance test for the tuning camera group is the first test in the series of tests in the northwest high-proportion new energy grid system characteristic verification series specifically for the new energy distributed machine group, and it is also a powerful practice for Qinghai power grid to build a new power system with new energy as the main body.
According to Wang Dongyang, commander-in-chief of the test site and The Chinese Academy of Electrical Engineering, 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.
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 a wider range and accelerate the clean transformation of Qinghai's energy, Qinghai Electric Power innovated and promoted the active support technology of new energy, 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", and greatly improved the ± 800 kV Qingyu UHVDC delivery capacity and regional new energy consumption.
