All energy & utilities environment are hazardous areas and need very reliable communication network to ensure realtime, accurate communication, data transfer. Production sites are having SCADA- Supervisory Control and Data Acquisition, which is used for monitoring, controlling plant activity. This is based on Ethernet interface.

There are two types of communication network used in energy- petrochemical sector. (i) Wired (ii) wireless. Both technologies are used in all segment & they complement each other. Wired technology is based Optical Fiber, Ethernet based system and provides faster data transfer while Wireless technology have own benefit and used for onsite communication majorly.

Oilfield communication includes technologies such as very small aperture terminal (VSAT) networks, fiber optic-based communication networks, microwave communication networks, cellular communication networks, and tetra networks. Power Line Carrier (PLC) is other widely used communication methodology.

Fiber Optics

Fiber optic sensors and cables are commonly part of Enhanced Oil Recovery (EOR) methods used to improve efficiency during upstream production, downstream transport, and refining of crude oil and natural gas. One popular EOR technique is Steam Assisted Gravity Drainage (SAGD), which uses DTS (distributed temperature sensing) to provide oil and gas operators with a reliable and cost-effective way to better manage reservoirs, wellbores, and completions.

Many oil and gas companies rely on proper installation and accurate operation of their systems. OTDR technology is often used when a fiber line is installed in an oil well, and to check the line before a DTS run to ensure the most precise readings are made.

Power generation plants to HO or regional office communication is based optical fiber technology and many power transmission companies have fiber based communication network along with transmission line. OPGW is popular technology used in power transmission.

Offshore Wireless Communications

Oil and gas companies are also using wireless technologies to gather and transmit critical data that aid in managing drilling equipment, pumping systems, and level monitors. Wireless technologies are integral in voice and data communications between offshore rigs and ships, and mainland operations, as well.

Reliable communications services – whether it is broadband satellite, high-speed Internet, SCADA (Supervisory Control and Data Acquisition), Wi-Fi, or VHF radio backhaul services – help in one other critical way. They help create a safer work environment for personnel.

Traditional base station transceivers usually consist of some antenna(s) being fed signals via long runs of coaxial cable or waveguide, and usually also contain protective elements like lightning arrestors (polyphaser for example) and may also contain filters, combiners, amplifiers etc… These elements must all be operating within their design specifications in order to maintain a robust communication link between the mainland and offshore equipment. Portable, handheld Cable/Antenna Analyzers or hand held Vector Network Analyzers are ideal for installation, maintenance, and troubleshooting of these systems.

More modern base station transceivers are typically more integrated, with the majority of the required hardware residing within a single radio unit which is mounted on the tower near the antenna(s). These systems are typically fed digital data signals through fiber optic links, although in some cases they may be fed digital signals through CAT 5e or CAT 6 twisted pair cables. These types of systems will require more over the air (OTA) testing to verify that the transmitted signals are as expected. A hand held Spectrum Analyzer with signal analysis capability is a very useful instrument for verifying proper operation and/or troubleshooting these types of systems if a problem does occur.

Smart Grid

Wireless technologies are also being used onshore by utility companies, as part of smart grids that help improve customer service and better control energy consumption. A smart grid system consists of home area networks (HAN), field area networks (FAN), and wide area networks (WAN). Each requires robust signal coverage to avoid interference. Utilities must have tools to effectively plan their systems, rapidly diagnose problems and maintain network security.

Indoor and outdoor coverage mapping tools provide utility companies with powerful and sophisticated analysis capabilities directly suited for their smart grid networks. These tools can aid in network planning, optimization, and maintenance of network infrastructure, saving utilities time and money.

Specific goals of the Smart Grid

• Allowing consumers to actively participate in optimizing operation of the system
• Reduce the environmental impact of the electric supply system
• Add robustness to the network by introducing new self-healing technologies
• Integrate ‘smart’ appliances and consumer devices as part of the system
• Dynamic optimization of grid resources
• Development of standards for communication and interoperability of equipment connected to the grid

Test Needs

The ability to analyze signal integrity in a wireless environment has long been realized by cellular carriers, satellite companies and other network providers as a crucial element in deploying and maintaining a secure system. As utilities deploy the Smart Grid with various wireless technologies, the need to access signal coverage and sources of interference will grow exponentially. Additionally, cable and antenna analyzers are needed to install, provision, maintain and troubleshoot wireless base station cable and antenna systems.

Utilities need to be able to analyze communication problems quickly and insure that their wireless network continues to run under a variety of conditions.

Telecom Test and Measurement (T&M) Instruments in Energy & Utilities

The utility communication market is expected to witness significant growth across the world soon owing to automation requirement. This communication system allows well-regulated and efficient transfer of utilities such as power or gas or hydro.
In order to keep communication network live, power utilities companies need to maintain communication network using various test and measurement instrument. Some of the widely used T&M and their application areas are listed here.

OTDR:

OTDR stands for Optical Time Domain Reflectometer & is required to test optical fiber link, detect fault location in plant and between plants, its HO, RO etc.

Power Meter & power sensors

Power Meter and sensors are required in checking transmitter power and improve coverage., optimize transmitters.

Summary:

Most of plants/sites are located outside main town or remote location and plant temperature is extremely high. So, communication infrastructure must be able cope up this environment. At the same time test instrument must be able to accept these extreme environment conditions. Certain sites might have high humidity, heavy machinery as well which impact smooth communication (wireless specifically). Therefore there should be wired and wireless communication (hybrid) network and it should be updated with technology & time. With digitization and automation acceptance in industrial sector, we expect there will be more and more connected machines inside plant and these machines will generate huge data. This data will be used for further report and analysis for better efficiency and operation of plants.

The utility communication market is expected to witness significant growth across the world in the near future owing to automation requirement. This communication system allows well-regulated and efficient transfer of utilities such as power or gas
As per Verified Market Research Report Utility Communication Market was valued at USD 10.96 billion in 2019 and is projected to reach USD 31.27 billion by 2027, growing at a CAGR of 15.1% from 2020 to 2027

Internet of things (IoT), Industry 4.0 , Machine Learning will modernise plants and need a secure communication network- internal and external. Power grids being connected all time need better cyber security arrangement and must be ready to face associated cyber threats.

A big challenge for utilities is the development of two-way communication systems that can support a large range of applications and requirements. Anritsu is contributing to this effort with test and measurement instruments that make it easier and faster to enable Smart Grid communications.
