Abstract

In the emergency repair of electric power caused by sudden natural disasters, the reliability and stability of emergency power supply vehicles largely determine the speed and efficiency of restoring power supply. Based on the performance test and reliability study of 18 diesel-powered vehicles in Guangzhou Power Supply Company Limited, the typical defects of emergency power supply equipment and the causes of the faults are analyzed. It provides technical support for the technical standards and the maintenance guidance of emergency power supply equipment, and greatly improves the emergency capability of rapid power recovery under extreme natural disasters. It has improved the emergency response capability of rapid re-powering under extreme natural disasters, shortened the repair time, and significantly reduced the loss and impact of extreme natural disasters on the power system and the entire national economy.

Highlights

  • In the emergency repair of electric power caused by sudden natural disasters, the reliability and stability of emergency power supply vehicles largely determine the speed and efficiency of restoring power supply

  • There is no national standard and industry standard for emergency power supply vehicles used in power grid emergency repairs

  • The aim of this paper is to study the related technologies of emergency power generation equipment, and to improve the quality, operation and reliability of emergency power generation equipment by establishing technical standards, technical specifications and operational guidance of emergency equipments[3,4]

Summary

3Reference Standards and Performance Parameters

This research work is carried out strictly in accordance with the requirements of China's national standard GB/T 20136-2006 "General Test Methods for Internal Combustion Engine Power Stations", industry standard. YD/T 502-2007 "Diesel Generator Set for 25 %, 50 %, 75 %, 100 % of rated load, reduce the Communication" and relevant technical agreements of a load from 100 % to no-load step by step according to this power supply bureau. When the technical load; Test the three-phase voltage, frequency and output agreement is lower than the national standard, industry power under various load levels. According to relevant standard or enterprise commitment, the higher technical requirements, the deviation between steadyrequirements in the national/industry standard or state voltage and rated voltage shall be ≤±0.5%, and the enterprise commitment shall be taken as the performance deviation between steady-state frequency and rated judgment basis

The performance and parameters studied include
