This paper studies the key technologies in the automation transformation of natural gas power plants. To meet the core needs of precise regulation

intelligent operation and maintenance

and safety prevention and control

it constructs a key technology system including distributed control system (DCS) upgrading and optimization

intelligent perception and data collection

unit linkage control

intelligent operation and maintenance with fault diagnosis

and safety protection with compliance management. The results show that these technologies realize precise unit operation

intelligent operation and maintenance

and comprehensive safety prevention and control

improving power generation efficiency

peak regulation capacity and equipment availability

while reducing energy consumption and operation and maintenance costs.
