Key tasks for equipment management in 2020

1. Main Objectives

Working ideas: Adhere to the concept of safe development, implement equipment management responsibilities, highlight source prevention and comprehensive management, pay attention to basic guarantees and status control, promote management changes and technological innovation, work hard on the "three transformations" of equipment management (standardization, leanness, and intelligence), seek breakthroughs in the "three alls" (full life asset management, full process technical supervision, and comprehensive quality management), improve the quality and efficiency of equipment management, and provide safety guarantees for the company's high-quality development.

Work objectives: In terms of safety, we will achieve "three eliminations and three preventions", that is, we will eliminate large-scale power outages, personal death accidents, and major equipment accidents caused by equipment management responsibilities, and strictly prevent major fires, malicious misoperations, and major network security incidents caused by management responsibilities. In terms of indicators, we will achieve "three reductions and three improvements", that is, the average number of DC single-pole locking times, 500 kV and above transmission lines, and substation equipment failure outage rates will be reduced by more than 5% year-on-year; the energy availability of DC projects will be increased by more than 5%, the reliability of urban and rural distribution network power supply will be increased to 99.967% and 99.838% respectively, and the urban and rural comprehensive power supply voltage qualification rates will be increased to 99.995% and 99.750% respectively.

II. Key Tasks

In order to coordinate this year's work, the State Grid Equipment Department has identified 35 key tasks in 10 areas (see the attached table for detailed plans). All units must make every effort to promote and fully complete all key tasks.
