Smart Dispatch For Power Dispatch Services

Smart Dispatch Integrated Network SolutionFor Power Dispatch Services

Solution Overview

For requirement of safety and reliability, power dispatch • system usually needs the dedicated network carrying services, divided into real-time, non real-time and emergency services. Services VPN division is used with QoS scheduling parameters configured individually to ensure critical business low latency and packet zero loss. The network ensures its reliability by full redundancy and fast switch-over.

Power dispatch network is usually divided into 3 layers •

as following

Core layer, in dispatch center and backup dispatch »center, to terminal all the substations and plants'

dispatch VPN services. The nodes in core layer

Solution Highlights

Huawei's smart integrated solutions for power dispatch network are dedicated to solve the power dispatch business concerns, through the network, equipment and overall reliability design, to provide non-stop power dispatch service. The refinement of service deployment with MPLS VPN and MPLS HQoS technology, more in line with real-time scheduling business needs, achieves dispatch business proprietary quality assurance. MSTP/WDM transmission and router combination solution based on IP & optical transmission provides super-long distance high reliability. Program based on 1588v2 solution can effectively achieve high-precision time synchronization between different power plants and substations.

are fully redundantly configured to ensure dispatch

business non-stop. The source timer can be deployed in

this layer, to provide standard synchronized signal.

Backbone layer, is in big substations and other control »stations. The backbone routers, connected by STP/

WDM and MPLS/IP network, to implement long

distance and high reliability forwarding, ensures safety

isolation and high quality for key services.

Access layer, is in substations and power plants. The »access routers aggregate site's services and uplink to

remote dispatch center. MPLS VPN is used for service

isolation. As big and important substations/plants,

dual access routers can be used, and for other sites,

single router with dual engines can be used, to ensure

dispatch service reliability.

Chal lenge: • SGCC(Sta te Gr id

Corporation of China) is the biggest

Power Grid company in the world,

serving 26 provinces and more than

one billion population of China. To

achieve the goal of strong & smart

grid. SGCC needed to build a national

grid network backbone with very

high reliability. The whole network

must eliminate single failure, and

failure of any node must cause services switched to backup routing within 500ms.

Solution: • Huawei relies on its 10-years large-scale network construction experience, to build the national backbone network

based on dual-plane transformation. NE40E routers are used in backbone of two planes, involved in the nodes in headquarters,

5 regions and 25 provinces. This program used the topology of two identical flat network architecture, running two separate IGP

routing planes with L3 VPN MPLS BGP, to achieve safe isolation of services.

Benefits: • Dual-plane construction of the backbone network greatly enhanced the reliability and stability of the whole network,

to support the strong, efficient and self-healing smart grid. Huawei's E2E high reliability ensured entire network 200ms protection

switch-over; Huawei complete MPLS H-QoS provided a safe business service quality isolation and low latency. In addition, Huawei

routers support 1588v2, to provide precise clock synchronization function for future evolution.

Solution Overview

2-levels network architecture is proposed to adopted in •

integrated data network. Substations or other enterprise

units are managed by regional center, which is in charge

of corresponding regional office, including management

and communication services. The core layer in HQ center

aggregates the entire services by MPLS VPN. Due to

differentiation existing in each region, nested VPN is

adopted, as the regional center combines local VPNs into a

big VPN and then uploads to HQ.

Power integrated data network is usually divided into 3 •

layers as following

Challenge: • Zhejiang Power Company was

committed to develop real-time monitoring of

remote control electric power running operation,

to ensure that the distribution system switch from

passive response to active maintenance with fast

fault. The ADO network covering the entire city's

power distribution network was established,

with the requirement of very high reliability and

environment adaptability.

Solution: • After complete tests, GPON solution

was used. OLT was placed in 110KV or 35KV

substations and other communication rooms,

communications cable extending along the

power line distribution network of electrical

equipment. ONU ring was placed in the cabinets

and other outdoor power equipment. Design by

ODN significantly enhanced the user experience.

Benefits: • GPON solution saved fiber resources, to enhance

network coverage, and to save significant cost. ONU devices

have a good environment for tolerance, high temperature, anti-

magnetic anti-lightning. Network in real time and high reliability

enhanced customer experience.
