Haras de Jardy: Topkapi for responsible lighting management
Street lighting is a budget item to which the public authorities are paying increasing attention, especially as it alone accounts for about 40% of their electricity expenditure. Faced with rising energy costs and growing environmental awareness, local authorities are working to improve the efficiency of their public lighting networks. To achieve this, the use of new technologies is in great demand, both to reduce consumption and to optimise use. Topkapi SCADA software allows to answer this problem.
Owned by the Hauts-de-Seine General Council, the Haras de Jardy is primarily used for equestrian sports, with 20 tennis courts, a golf practice and a nine-hole-golf course. These three sports have very high quality sports and leisure facilities provided by the County Council.
An ambitious lighting management renovation programme
At the instigation of the General Council's leaders, an investment programme has been voted on for the renovation of all the external lighting in the facilities, the objectives of this programme being :
- to bring the installations into electrical conformity (standards C15-100 and C17-200 relating to public lighting installations) for the safety of goods and people;
- make the installations more reliable ;
- manage and monitor the operation of the equipment ;
- ensure preventive maintenance ;
- to offer a very good quality of service to users of the infrastructure;
- give autonomy to the delegated parties in their management of the facilities under their responsibility;
- raise their awareness of energy savings and maintenance costs.
Spie's choice of Topkapi supervision software
The contract was then awarded to SPIE (95 - Cergy Pontoise) represented by Messrs NOWINSKI and JEZEQUEL for the realisation.
The application in a few figures :
- An Ethernet TCP/IP Modbus fibre optic network of 4 km ;
- Manageable input/output blocks and switches from Phoenix Contact are included in the scope of supply;
- A Schneider Premium Supply Vending Machine ;
- Two redundant Topkapi hot servers and a Netview client ;
- 23 boxes, eight starters/boxes for a total of almost 184 light points ;
- Three areas of use: horseback riding, tennis/golf, footpaths and car parks.
Each area is operated by a different entity: one delegate for golf/tennis, one delegate for horse riding. The General Council retains the operation of the paths and car parks which are free of traffic for the general public. Hence the need to equip the site with three supervision stations (one per zone), each user having access after identification only to the part of the application that concerns him/her.
The choice for the supervision architecture was oriented towards Topkapi hot redundancy with a customer for the following reasons:
- availability and security of the application ;
- unique database ;
- traceability of operator actions for the General Council ;
- autonomy of the delegatees in their management.
The system allows all the light points in the park to be switched on and off with the possibility of calendar planning (particularly for the lighting of tennis courts according to occupancy where the Topkapi Scheduler tool is used), twilight management (an astronomical clock is associated with the PLC) and operation in automatic/manual/forced mode as required.
It also enables the operating time of each start to be counted, thus enabling the replacement of light sources to be monitored and anticipated. This is an important act of preventive maintenance to ensure the safety of men and horses during the riding part of the event.
According to Mr Yann CARER of Spie, the company that led the project and developed the supervision application, Topkapi has undeniable assets to meet this type of project:
- design of a library of synoptic objects that are customised and scalable for the application, which has enabled significant time savings to be made in order to meet the changing needs of operators;
- client/server architecture and redundancy very easy to deploy by simple parameterisation ;
- multiple functions integrated into the product (calendar, plan management, GUI scripts, PLC database import via Softlink wizard, popup windows, etc.) enabling productivity gains in application development.
For Mr DEVIENNE and Mr GOWREEA of the General Council, "the objectives of the project have been achieved" and they were particularly marked by "the simplicity of the application's operation" which is used today by people who are not familiar with automation, thanks in particular to the ergonomics proposed by Spie.
The next step could be the implementation of a specific electrical energy metering system allowing a better control of the costs related to the external lighting of the park and an optimal follow-up of the installations through energy balances generated by the Topkapi SCADA software.
