• Substation Automation, Power and Distribution Management Systems
The commencement of having the SAS technology in Iran was in Kazerun 230kV Power Plant Substation and consequently Abadan 230kV P.P. Substation and Damavand 400kV P.P. Substation. Ray-Avin-Fan Managers and staff are honored to participate in these projects since the very beginning phase of signing contract up to final take over to client in all aspect of Commercial, Technical and Execution. Having this background Ray-Avin-Fan is confident to handle similar projects. This includes know-how transferring, Engineering, procurement and commissioning along with Training of the End users staff in order to operate and maintain the systems in the optimized way.
Since Iran is a country under development, potentially there is a good opportunity in the Fields of Power Management Systems (PMS) and Distribution Management System (DMS). There are so many inland and offshore utilities that producing their Electrical Energy up to 10s of MWatt and may have connection to national grid. They are mainly active in Oil and Gas and Petrochemical Industries, Mine and Metal Complexes and other Industrial factories. Due to comparable large amount of Energy that these utilities produce and distribute, the importance of their process and dependency of it to the quality of electricity, benefiting from a Control, Monitoring and Managing system is vital to facilitate their network Operation from one hand and shortening and reducing of the maintenance time and cost from other hand. Therefore utilizing DMS and PMS is becoming a must for these utilities. Ray-Avin-Fan participates in this field as a pioneer and offers different scalable solution according to the Clients’ conditions, requirements and budgets. Know-how transferring, Training and Support is among our major policies, making the Clients as independent as possible for Operation and Maintenance.

• SCADA Systems and Dispatching Centers
In not very old days in Iran, Networks used to be controlled locally, without considering the situation in the neighborhoods but sometimes affecting them or getting affected from them by malfunctioning. Nowadays by getting more complicated networks’ and their high amount of generation and consumption, great tendencies exist to Supervise, Control and Managing the whole network from one or several Remote Centers with a defined hierarchy. This fact in Electricity, Water, Oil and Gas and Railways Networks enables Clients to have the best maneuverability over their network and assist and improve intelligent decision-making because of presence of statistic.
Ray-Avin-Fan is able to offer the best solution as well as dedicated Software and Hardware for a specific Project according to the Client budget. This could be handled either as the Main Contractor facing the Client and/or in the format of joint ventured with reputable International Companies.

• Power Management Systems (PMS)
The high dependency of some industries on the quality and availability of Electrical Energy demands a certain level of Energy Management who is able to comply these requirements from Generation, Distribution and Consumption aspects. Power Management Systems is an absolute answer to this requirement which not only can reduce the peak demand of the load but also with the assistance of functions like Load Shedding, Load Restoration, Source Transferring, will increase the availability of the load supply. The stability in Voltage and Frequency of the Supplies are other advantages of PMS.
The PMS technology is mostly used in Oil, GAS and Petrochemical Industries, Marine, Industrial complexes and Utility plants that have sensitive and essential loads.
Having a great support from worlds most reputable manufacturers and system developers and with the assistance of the country’s most reputable panel manufacturer Ray-Avin-Fan Co. is able to furnish the first class EPC services on this System.

• Distributed Control Systems
The necessity of optimized utilization from Industrial Complexes from one side and the essence of maintaining the integrity of them despite of the complexity of the technology, have created a tendency for Industries towards Distributed Management Systems (DCS). But implementation of DCS requires two fundamental prerequisite, first knowing the process and it’s requirements and also the field instrumentation, second having a background of IT knowledge.
Utilizing these two powerful arms powered Ray-Avin-Fan to design and implement the Telemetry, Monitoring and Control of PLC based Systems and RTU based Systems for Oil and Gas, Chemical, Electrical, Water and other different industries.
Although this company is based on electrical, control and instrumentation engineering, it has a powerful staff for process, piping and safety services in his projects. Therefore in design, procurement, installation and commissioning of projects, this company not only performs the instrumentation and control activities, but also can have full cooperation in process, piping and safety branches of projects.

• Developing and Simulating of Communication Protocol Converters
In not so far old days and even in recent years, communication protocols that have been used for sending and receiving the Telemetry and Control information from Fields to Centers and between Centers were not standardized. These protocols are mostly developed by the Technological Giants and somehow have becoming defacto standards, however in the most of cases these protocols were not able to communicate with each other. Upon vast development of the Automated Systems, Internet and Computers from one side and releasing of new “Open System and Protocols” by standard organization from the other side, the advantage of using of different systems and installation as well as Monitoring and controlling them from different corners is becoming a truth. To satisfy this uprising demand, one has to comply and coordinate the existing and old plants systems with the new standards. And the definite right tool for making this coordination is nothing but Protocol Converters and Simulators.
Having a basic and advanced knowledge of the old and update protocols such as MODBUS, DNP-3, PROFI-BUS, LON, TG800, IEC60870-5-101, IEC 60870-5-103, ETC, gives us the power to develop any sort of protocol converters for the proprietary protocols of the Utilities and Industries.
