0 introduction

In recent years , Driven by the national fiscal policy , China's expressway continues to develop rapidly . City 、 The convenience of inter provincial transportation is guaranteed by highways , Speed up the product 、 personnel 、 Information exchange , Convenience has changed people's way of life , It has promoted the development of the national economy .

With the rapid development of Expressway , The increase of process makes the contradiction of operation inefficiency increasingly prominent , How to manage reasonably and ensure stable operation has brought certain challenges to expressway .2010 Since then , The state has promulgated a series of policies to promote the standardization of expressway industry 、 Policies and regulations for information operation , Make the expressway intelligent 、 Informatization has become the general trend of development . Vehicle detection system 、 Environmental detection system 、 Video monitoring system 、 The charging system has become an essential part of high-speed intelligent informatization , However , The normal operation of these systems is inseparable from the electromechanical system , The importance of power supply and distribution monitoring system can be imagined .

Acrel-3000WEB As a relatively independent system, the electric energy management system is the Duba high-speed power supply and distribution system 、 The intelligent system has laid the foundation stone .

1 Project overview

Hezhou Bama Expressway （ Du'an Bama section ） It is called Duba expressway for short , Duba expressway is a county to county expressway project mainly promoted in Guangxi , The whole length of the main line 119.129 km , The geological conditions are complex 、 Difficult construction , Bridge and tunnel Bida 46.25%. There are 27 A tunnel ,5 Toll booths ,2 A service area ,2 A parking area ,1 Monitoring centers , Co distributed 59 Distribution rooms and box type substation and distribution stations .
