The problem of digitalization of the data accounting system and the problem of managing the technical condition of equipment at thermal power plants are considered. The performance of the entire thermal power plant depends on the operation of the boiler units. If the equipment fails and the necessary measures to resolve the emergency are not taken in time, then the probability of a decrease in the plant's performance up to the suspension of work increases. Thus, the issue of monitoring the technical condition of all operating equipment is relevant. The developed software for automation of the data recording system and visualization of technical parameters of the reliability of boiler and turbine equipment is described. The software has a methodology for determining the technical condition index of equipment. The software was developed using the JavaScript programming language, the React.js library. Digital technologies have been introduced into the process of recording data on the technical condition of equipment, where for the first time the software includes a method for automatic calculation of the technical condition index of boiler units. The software ensures that equipment downtime is reduced, as well as the likelihood of failure or critical breakdown of boilers. Thus, the operation of the software makes it possible to reduce the likelihood of an emergency state of the main equipment of power plants.
