Common precautions include: deployment of hardware equipment: the equipment backup and redundancy system is increased, and the reliability and stability of the power grid equipment are improved; and (3) formulating a data acquisition strategy: the frequency and time of data acquisition are reasonably arranged, so that data congestion and abnormal conditions are avoided; establishing an emergency plan: an emergency plan is formulated for emergent situations, so that timely response and processing can be realized; and (3) reinforcing equipment inspection and maintenance: checking and maintaining the power grid equipment regularly to ensure the normal operation of the equipment; introducing a new technology: by adopting the new technical means and method, the accuracy and timeliness of the power transmission capacity monitoring of the power grid are improved. In order to ensure the normal operation of the power grid, continuous monitoring is performed. Continuous monitoring includes periodic collection of data, data analysis, visual presentation, and the like. Through continuous monitoring, abnormal power transmission capacity of the power grid can be timely found and corresponding measures are taken for processing, so that stability and reliability of the power grid are ensured. Meanwhile, continuous monitoring can also provide data support and reference basis for business decisions of the power company.
