Rethinking domestic power construction by blackouts in India



According to the Voice of Economy's "World Financial" report, India suffered the largest power outage yesterday (1st), which was the third power outage in three days. The failure of the main grid in all 28 Indian states and seven associated territories caused an estimated billions of dollars in losses to companies and left 1.2 billion people in darkness.

It is not difficult to see that this blackout is a major hit for India’s economy and image. So what caused the accident?

According to the analysis of related power analysis experts, long-term power supply is seriously deficient, power grid construction has been lagging for many years, and the grid structure is weak, which is the main reason for this blackout in India. In addition, the State Grid Corporation of India has mastered the basics of the central power transmission. The power distribution is run by various state power bureaus and private power supply companies. The lack of a unified dispatch management mechanism is also an important reason why power failure cannot be resolved in time.

China has similarities with India in terms of electricity supply. India's energy is mainly concentrated in the east, and the load is mainly in the west and south, and the power transmission is mainly sent from East to West. China's energy is mainly concentrated in the northwest and Inner Mongolia, and the electricity load is concentrated on the eastern coast. The power is sent from the west to the east, and from north to south. Both countries need to transport large volumes over long distances.

Therefore, this large-scale accident in India has a great warning effect on China. It is necessary for China's electric power construction to reflect on and learn from this.

The national grid responded quickly. On the afternoon of July 31, the State Grid Corporation of China convened a special conference on major blackouts in India. From this week onwards, a major safety inspection was deployed to sort out the grid and eliminate hidden dangers. The safety activities are mainly to strengthen the risk assessment and analysis of the power grid, to find the safety risk points of the power grid and the status of the equipment to conduct hidden investigations; to conduct safety education for the personnel; to scientifically arrange the power grid operation modes, and strictly control the ultra-stable limits and equipment capabilities of the power grid. Run to prevent overload.

State Grid believes that in order to prevent this from happening in China, on the one hand, it is necessary to increase the interconnection of the power grid, adhere to the integration of transmission and distribution, integration of power grid dispatch, and integration of urban and rural areas. On the other hand, we must promote smart grid construction and form a unified smart grid with a strong structure and complementary resources. In addition, UHV has also been regarded by the industry as the direction of China's power grid construction in the future.
