Abstract: The“7.30” and“7.31” two serial blackout events in India show many issues in the managerial mechanism of power industry, potential operation risk prevention and power grid planning and construction. The current situation of Indias energy and power development is introduced and the direct reasons for these two blackout events are uncovered, that is, the system frequency in each region is too low and power oscillation happens later, which leads to system collapse. Considering the current situation of Indias power industry, the in-depth reasons and the lessons from the events are also dissected, which presents that the security and operation control system for large power grids with unified planning, unified dispatching and unified management is weak. Consequently, the revelation and recommendations for China focusing on power industry development are put forward.
