Electrical secondary equipment state evaluation method and system thereof

The invention provides an electrical secondary equipment state evaluation method and a system thereof. The method comprises the following steps: presetting a weight proportion of each maintenance state parameter of secondary equipment to a maintenance state value of the secondary equipment, and establishing a calculation model of the secondary equipment maintenance state value; acquiring real-time detection values of each maintenance state parameter of the secondary equipment, calculating the maintenance state value of the secondary equipment according to the calculation model of the secondary equipment maintenance state value; determining a maintenance state of the secondary equipment according to a calculation result of the maintenance state value of the secondary equipment. According to the method and the system provided in the invention, the maintenance state of the electrical secondary equipment of an electrical system can be determined comprehensively in order to maintain the electrical secondary equipment timely and prevent various fault problems brought by lack of electrical secondary equipment maintenance.
