It also provides the FCC compliance information. Purpose The purpose of this document is describe to the user the purpose, components, operation and communication method of the SmartBypass. Abbreviations Term Definition A RMS Amperes Root Mean Squared SCR Silicon Controlled Rectifier MOV Metal Oxide Varistor NC Normally Closed ISM Industrial, Scientific, and Medical Radio Band Table 1: Abbreviations General Product Overview Smart Wires’ SmartBypass technology is designed to protect other Smart Wires series compensation devices. The SmartBypass does this by automatically activating switches to carry the transmission line current during line faults or when operators desire to manually bypass the series compensation. The SmartBypass technology builds on the protection used in other Smart Wires products, like the Power Guardian 390 which has internal protection on the secondary side of its injection transformer. The SmartBypass is installed on a single-phase basis, meaning that for most transmission deployments, there will be an equal number of units per phase. Figure 4-1: SmartBypass with Mounting Bracket and Corona Rings © 2019 Smart Wires | www.smartwires.com Page 3 of 7 D000587 SmartBypass User Guide Revision A Electrical Operation of Single Module The SmartBypass comes in several different models as shown in Table 2. The SmartBypass can operate at line currents of thousands of amps during normal bypass operation and withstand different fault current levels depending on the model. The SmartBypass models are differentiated by continuous current rating and maximum fault current rating. For example, the SmartBypass 4000-63 is rated for continuous line currents up to 4000 A RMS and fault currents of up to 63 kA RMS for 1 second. The SmartBypass provides telemetry when operating in monitoring mode or injection mode. The SmartBypass operates to protect the power electronic components within Smart Wires series compensation devices by operating when the devices are switched in series with the line, when a fault occurs on the line and when the devices are switched out of series with the line. The SmartBypass can bypass Smart Wires series compensation devices within in 1 msec of the inception of a fault, thus ensuring the protection of internal power electronics of the devices. Figure 5-1 illustrates the basic electrical configuration of the SmartBypass. 5.1 Enclosure 5.2 Inductors 5.3 Normally Closed (NC) Contactor 5.4 Silicon Controlled Rectifiers 5.5 Metal Oxide Varistor The enclosure of the SmartBypass is connected to the transmission line at one terminal, this ensures the enclosure is at line potential. All other terminals and components are insulated from the enclosure. Each SmartBypass contains two small inductors, represented by L1 and L2, one on either side of the normally closed vacuum series link, S1. The inductors ensure the voltage across S1 is close to 0 V when S1 opens and closes, extending the lifetime of this component. The normally closed contactor, represented by S1-NC, carries the current when the Smart Wires series compensation devices are bypassed under normal conditions. S1 is what determines the continuous current rating of the SmartBypass, S1 can carry either 2000 A RMS continuously or 4000 A RMS continuously. Each SmartBypass contains one or more pairs of anti-parallel silicon-controlled rectifier (SCR), shown as S2 in figure 2. The SCRs carry the line current in the case of a fault or when S1 operates to switch in or switch out the Smart Wires series compensation devices. The SmartBypass is equipped with a metal oxide varistor, MOV1 in Figure5-1. MOV1 protects the internal components of the SmartBypass from high current events such as lightning strikes. © 2019 Smart Wires | www.smartwires.com Page 4 of 7 D000587 SmartBypass User Guide Revision A Model SmartBypass 2000-63 SmartBypass 2000-50 SmartBypass 2000-38 SmartBypass 2000-25 SmartBypass 2000-12 SmartBypass 4000-63 SmartBypass 4000-50 SmartBypass 4000-38 SmartBypass 4000-25 SmartBypass 4000-12 Continuous Current Rating (A RMS) 2000 2000 2000 2000 2000 4000 4000 4000 4000 4000 Maximum 2-Hour Emergency Current (A RMS) 2160 2160 2160 2160 2160 4320 4320 4320 4320 4320 Fault Current Rating (kA RMS for 1 s) 63.0 50.4 38.0 25.2 12.6 63.0 50.4 38.0 25.2 12.6 Peak Fault Current (kA) 60 Hz 50 Hz 164.0 131.0 98.8 65.0 32.0 164.0 131.0 98.8 65.0 32.0 158.0 126.0 95.0 63.0 31.5 158.0 126.0 95.0 63.0 31.5 Table 2: SmartBypass Models and Specifications Figure 5-1: SmartBypass System Diagram SmartBypass Control The SmartBypass has 2 distinct modes of operation, the performance and operation of the modes is described below. 1. Monitoring Mode – The normally closed contactor S1 is closed. The SmartBypass bypasses the Smart Wires series compensation devices across its terminals so no reactance is injected. The SmartBypass can transmit telemetry data in this mode. When the SmartBypass senses a line current which exceeds its rated tolerance, it automatically bypasses the Smart Wires series compensation devices with fast‐acting antiparallel SCR switches (S2), entering monitoring mode within 1 millisecond. © 2019 Smart Wires | www.smartwires.com Page 5 of 7 D000587 SmartBypass User Guide Revision A 2. Injection Mode – The normally closed contactor S1 is open. SmartBypass allows the Smart Wires series compensation devices to inject their reactance across its terminals in series with the line. Product Components The individual components of the SmartBypass are shown in Figure 7-1. Figure 7-1: Individual Components of the SmartBypass A – Protection Circuitry – the Silicon Controlled Rectifiers (SCRs) are housed longitudinally along the interior floor of the unit. B – Yoke Plate – this plate is the fixture point for insulators supporting the unit from above. C – NEMA Pads – these are the electrical connection points for the unit. D – Corona Rings – surround both latitudinal sides of the device to prevent corona at high voltages. E – Normally Closed Contactor – the normally closed contactor is housed across the top of the inside of the enclosure parallel to the yoke plate. Wireless Communication The SmartBypass has the capability to communicate over a secure wireless Industrial, Scientific and Medical (ISM) band. The ISM Secure Wireless Mesh is the communication network protocol based on Radio Frequency wireless communication for between ground-based equipment and the SmartBypass. The SmartBypass support the 2.4 Ghz band in the US. The SmartBypass uses a frequency-hopping spread-spectrum solution. It does not occupy a single user-selectable-channel like, for example, WiFi does. © 2019 Smart Wires | www.smartwires.com Page 6 of 7 D000587 SmartBypass User Guide Revision A Regulatory Compliance User Notice: FCC: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules.
