Recently, the Rattlesnake project of Xinjiang Goldwind Technology Co., Ltd. successfully passed the Texas Electric Power Reliability Committee (hereinafter referred to as 'ERCOT') for the acceptance of a frequency modulation function of wind turbines. This project is a primary frequency modulation technology of Goldwind Technology. The first application case in the world is also the first application of China's wind power enterprise's primary FM technology in overseas markets.
The Texas Power Grid (hereinafter referred to as 'ERCOT Grid') within the jurisdiction of ERCOT is one of the most stringent grid-connected grids worldwide. The successful acceptance of this test indicates that Goldwind's FM technology has reached international standards, regardless of gold. Wind technology is still a milestone breakthrough for China's wind power industry. This successful case provides more support for China's wind power industry to go abroad and open up a broader international market.
North American grid distribution overview
Market demand creates stringent standards
Primary frequency modulation is inherent in the frequency characteristics of conventional generator set speed control systems, but has not been implemented in volume applications in the new energy field. ERCOT adopted NERC (North American Electric Reliability Corporation, North American Electric Reliability) since April 2015. The company's regional guidelines, in the operation, put forward a frequency assessment standard. In its assessment standard setting, ERCOT requires all power generation equipment in the power grid to have a frequency modulation capability, including wind farms with a capacity of more than 20MVA.
ERCOT specifies the required frequency range and technical requirements for all power generation equipment. ERCOT has detailed and detailed provisions in the commissioning and testing process and acceptance. During the operation of the project, ERCOT will also have the frequency of the power plant every year. Respond to the assessment.
In fact, primary frequency modulation technology has become a universal requirement of major power grid companies in North America. The North American power grid is at the forefront of the world in terms of technical standards, and to a certain extent represents an international trend. It is precisely because of its strict standards, super high 4. The wind power projects implemented in the region are facing the technical challenges of the highest international standards.
Faced with the stringent standards of ERCOT, Goldwind Technology calmly responded. Based on the key technology of wind farm virtual synchronization, Goldwind Technology independently developed the Virtual Synchronous Generator (VSG), which is composed of a unified hardware platform and a complete set of independent The software system consists of current domestic and international wind power grid-connected mainstream technologies to meet actual project requirements, including automatic power generation control (AGC), automatic voltage control (AVC), primary frequency modulation, high voltage ride through, anti-islanding capability, etc. The FM performance is adjustable by 10% Pn, and the response time is up to 500ms.
Provide technical support and solutions for wind power stability and friendliness
In view of the different characteristics of energy, primary frequency modulation technology is relatively mature in the field of traditional energy power generation, but it still has a high technical threshold for the wind power industry. The realization of primary frequency modulation technology represents the technological advancement of wind power enterprises, which is in line with the development of the international wind power industry. Trends, in line with the higher standards of the international market.
At present, Goldwind's primary frequency modulation technology has been promoted and applied in many domestic projects. The American rattlesnake project is the first case that Goldwind Technology's primary frequency modulation technology is promoted in overseas markets and verified by local power grid. In the future, Goldwind will also This technology is applied to wind power projects in Australia, Chile and other places. At the same time, Goldwind Technology is actively participating in the development of a related FM industry standard in China, and shoulders the heavy responsibility of jointly promoting the development of domestic industry standards.
Goldwind's American rattlesnake project successfully passed the acceptance of ERCOT, which fully verified that Goldwind's technical capabilities have not only taken the lead in China, but its technological advancement has also been recognized and praised internationally. Goldwind has the ability to build first-class domestic and international The wind power project, which meets the most stringent grid standard requirements, provides strong technical support and complete solutions for wind power to become an increasingly stable and friendly power supply method, and contributes to the Chinese wind power enterprise entering the international stage.
Embracing 'Wind Power 2020', Goldwind Technology has confidence.
