The electrical grid is becoming smarter and far more integrated than anything seen by our predecessors. The smart grid, as it is called, takes advantage of distribution automation and control to establish an energy-efficient network capable of real-time monitoring and fault detection; thereby reducing outages and securing critical data.
Maxim helps build a secure, networked grid for advanced integration of distributed resources.
Constant challenges
Undoubtedly, a robust system of this magnitude is presented with numerous challenges that require the utmost high-performing analog solution to ensure that the lights always remain on. To emphasis the scale on which a smart grid needs to operate, consider the vast populations of people inhabiting cities; from tens of thousands to millions. In order to illuminate such cityscape, an even greater number of lights are required, each one being an endpoint in a connected network serviced by a distribution network. Any number of fault situations can simultaneously occur.
For this reason, the grid needs to encompass precise signal chains that are able to accommodate a wide range of impedances. The equipment must immediately respond once a fault is detected in order to isolate the malfunction and minimize downtime. Any persistent fault will autonomously be communicated to a repair.
Future prospects
Future smart-grid incarnations must deal with power demand taxed by growing populations amid an aging infrastructure and unknown weather conditions. There will be greater demand for even faster response and shorter fault durations than now. Moreover, the interconnectedness of distributed networks requires advanced security measures to protect against malicious cyber-threats.
Maxim Integrated’s expertise in incorporating precision analog and security allows the company to provide a robust and innovative distribution automation solution for advancing electrical grids. Such a solution adheres to the principles governing the smart grid in the first place: providing cleaner and more reliable energy than ever before.
The solution set
Allowing systems to quickly detect and correct faults requires heightened accuracy and speed. For this purpose, Maxim includes the MAX11040K 24-bit four-channel ADC. Alternatively, the MAX11046/MAX11056 16-bit 4-/6-/8-channel ADC is another option.
To increase overall flexibility without sacrificing efficiency, the MAX17501/MAX17502 60-V synchronous buck temperature sensor and the MAX31865 RTD-to-digital converter are also included in this solution.
The last component in the selection plays a chief role in protecting the distributed network against security risks associate with cyberspace. The DeepCover Secure authenticator (DS28E25) and DeepCover Secure Microcontroller (MAXQ1050) protect equipment through their entire lifecycle.
