Research on the measurement method of primary equipment technical transformation investment demand based on the statistical analysis of equipment scrap time probability

In recent years, with the change of the operating environment of power grid enterprises and the increasing investment in power grid construction, the stock of fixed assets of power grid enterprises has been greatly increased, and the technical transformation expenditure of fixed assets shows a trend of increasing year by year. Primary equipment of power grid is an important material guarantee to maintain and improve the production capacity of power grid enterprises, and accounts for a large proportion of the total assets. Among them, technological transformation investment is an important factor affecting the operating results and cash flow of enterprises. Most domestic power grid enterprises rely on historical experience and the application results of grass-roots units to make technological transformation and repair decisions and distribution, which is difficult to accurately grasp or predict the scale of future technological transformation projects, and cannot effectively measure the matching situation between the investment scale and the scale and status of assets. Therefore, it is of great practical significance to carry out the calculation and research of the power grid primary equipment technical transformation investment demand to improve the asset operation and peacekeeping management level of the power grid enterprises.
