3 Agenda Powerline Communication 101 Modulation techniques Channel characteristics Applicable regulations Transceiver requirements No New Wires: Where and How Existing and potential applications Implementation challenges and solutions Market Trends Smart grid Standards and technologies 3
4 Powerline Communication 101 Why Powerline Communication? How it works? What are the typical challenges? Are there any applicable regulations? 4
5 The Good, the Bad and the Ugly No New Wires Send data on existing lines that transport electrical power High / Medium / Low Voltage AC/DC power lines Operate by superposing a modulated carrier signal on line voltage Narrowband modulation systems Broadband modulation systems Challenging conditions Unpredictable and widely varying channel characteristics Electromagnetic compatibility restrictions Emerging technologies and applications Slow development of acceptable standards and regulations 5
6 Once Upon a Time 1838 First remote electricity supply metering 1897 First patent on power line signaling 1920s First carrier frequency systems began to operate over high-voltage lines 1930s Ripple carrier signalling was introduced on the medium and low voltage distribution systems 1940s Emerge the expression Power Line Carriers (PLC) 1974 Early directive for transmitted power and frequencies 1980s Home-control PLC devices become available 1990s (X10, CEBus, LonWorks) 1997 First International Symposium on PLC (ISPLC) 2001 HomePlug 1.0 specification released 6
7 Broad and Narrow Narrowband PLC Broadband PLC Data rate Up to 200kbps Over 1Mbps Frequency Up to 500kHz Over 2MHz Modulation Applications Providers FSK, S-FSK, BPSK, SS, OFDM Building Automation Renewable Energy Advanced Metering Street Lighting Electric Vehicle Smart Grid Renesas Maxim ST Microelectronics Texas Instruments Echelon Yitran Cypress Ariane Controls OFDM Internet HDTV Audio Gaming Atheros Maxim Sigma Broadcom Lantiq Marvell 7
8 Single-carrier PLC Technologies FSK, S-FSK, BPSK, ASK An analog carrier signal is modulated by a discrete signal Digital data is represented by a finite number of distinct signals Proven performance (ex: X10, Echelon, ST, Ariane) Low complexity, low power, low cost Limited data rate (typically up to 10kbps) Sensible to narrowband noise (FSK) or phase distortion (PSK) Frequency Shift Keying (FSK) 8
9 Spread-Spectrum PLC Technologies DSSS, DCSK The original narrowband information is spread over a relatively wide band of frequencies The band spread is achieved by means of a higher data rate bit sequence Robust against narrowband noise Low spectral efficiency Limited data rate Few implementations (ex: Yitran) 9
10 Multi-carrier PLC Technologies OFDM A large number of closely spaced orthogonal subcarrier signals are used to carry data Each sub-carrier is modulated with a conventional modulation scheme (such as BPSK, QPSK or QAM) Emerging implementations (ex: PRIME, G3-PLC ) Robust against narrowband noise and multi-path propagation Higher data rates Able to adapt to channel conditions Increased complexity, cost, power consumption Large frequency bandwidth 10
11 Architecture of PLC Transceivers Signal Processing MCU Protocol Networking Application Modem PHY MAC Tx Rx DAC / ADC Filtering Amplification Coupling Circuit Capacitive / Inductive Protection Isolation Power Line AC / DC Power Supply Linear / Switched-mode / Capacitive 11
12 The Grid Transmission Grid High Voltage Lines Substations Medium Voltage Lines Distribution Grid Substations Low Voltage Lines Solar Farms Wind Farms Large Industry Small Industry Commercial Buildings MDU Homes 12
13 The Challenges Harsh medium for data communication Unpredictable and varying characteristics Time Frequency Location Limited and inaccurate theoretical models of power line environment Main technical challenges: Signal attenuation Signal distortion Noise 13
14 Signal Attenuation and Distortion Main causes: Impedance of connected loads Inductive, capacitive or resistive Can be as low as 1 Ohm Multiple phases Power transformers Wire impedance Reflection effects Highly varying with frequency and time Attenuation ranges between 10dB and 60dB 14
15 Noise Generated by loads connected to the power line Time, location and frequency dependent Main types: Continuous noise Time-invariant continuous noise (background noise) Ex: Thermal noise caused by internal circuitry Time-variant continuous noise Ex: inverter-driven fluorescent lamps Impulsive noise Synchronous to AC mains Ex: Thyristor-based light dimmers Asynchronous to AC mains Ex: Switching regulators Single-event impulses Ex: Switches, thermostats, capacitor banks Narrowband noise Ex: Interference from radio stations 15
16 EMC Standards and Regulations Frequency band allocation Maximum output power levels Electromagnetic emissions limits Conducted emissions Radiated emissions US FCC Part 15 for Carrier Current Devices 0kHz 535kHz Canada ICES-006 0kHz 535kHz Japan ARIB STD-T84 10kHz Europe EN kHz Band A Utilities B, C, D Consumer 3kHz 95kHz 148.5kHz 16
17 PLC Transceiver Requirements High transmission power capability Excellent receiving sensitivity High noise immunity Error detection and correction features Medium access mechanism Adjustable communication frequency Compliance with EMC regulations CENELEC EN50065, FCC Part 15, ICES-006, ARIB Data rate adapted to application requirements Low power consumption Low cost 17
