1 Rectifier Chassis (Typical) Control Chassis (Typical) The SSE Solid State Shunt Static Exciter/Regulator offers the perforance and reliability deanded by industrial and utility users. Basler's SSE utilizes solid state analog design to provide high initial response for iproved otor starting and fast voltage recovery. t ay replace the rotary brush type exciter, eliinating ost routine aintenance and repair. This static excitation syste has a high operating efficiency and low operating cost. On synchronous otor applications, the SSE ay be used with a Basler VAR/Power Factor Controller to autoatically aintain constant VARS or power factor on the otor during variations on otor loads.

2 "SSE" Shunt Static Exciter/Regulators The SSE consists of a control chassis, power rectifier chassis, and electrical power isolation transforer: all the eleents required to aintain generator terinal voltage within±%%. This is accoplished by onitoring the terinal voltage and coparing it to a voltage reference. Any difference developed fro this coparison causes an iediate change in the de output of the static exciter to the generator field to noralize the ac generator output voltage. Standard features of the static exciter/regulator include selection of single or three phase voltage sensing. A voltage liited Volts/Hertz circuit is standard. t is used to reduce generator voltage as a function of prie over speed. A user-selectable 1 P.U. or 2 P.U. Volts/Hertz circuit is available to prevent generator field and stator heating caused by low prie over speed. An LED is provided for indication during underfrequency operation. See Figures 2a and 2b. When ultiple generators are operated in parallel, a built-in reactive droop copensation circuit is used to balance VAR level sharing between generators to Regulation Better than ± WYo for load application or rejection after all transients have decayed Exciter/Regulator Response Less than 5 illiseconds Teperature Coefficient Better than 1% for a 5 C abient teperature change Autoatic Voltage Adjustent Range ± 1% noinal voltage Sensing Voltage 6Hz, ,28-24,416-48,52-6, ±1% 5Hz, 1-119, 22-24, , ± 1% Maxiu burden per phase: 1 OVA DESCRPTON iniize the circulating current that ay otherwise occur. A built-in anual control offers easy troubleshooting and reliable backup as an alternate for the autoatic voltage control. Voltage shutdown is accoplished by electronically shutting off the rectifier bridge or by a contactor, depending on exciter rating, causing an iediate decay of generator output voltage. Voltage buildup is accoplished by rectifying the residual voltage fro the generator output and applying it to the generator field. (A 5% iniu residual voltage is required.) The SSE ay optionally be equipped with a contactor to interrupt ac power for generator voltage shutdown. For positive generator voltage buildup, optional field flashing relays ay be selected to apply the station's battery power to the generator field. An overflash prevention circuit reoves field excitation when the generator voltage has not built up within a predeterined tie.

6 "SSE" Shunt Static Exciter/Regulators OPTONAL SSE STATC EXCTER ACCESSORES for enhanced syste perforance ENCLOSURE All eleents of the excitation syste can be ounted in a standard steel cubicle. The cubicle is rigid and self-supporting with full length doors in the low voltage copartent. Easy access is provided to all necessary controls and terinal points to ake installation easy and trouble-free. The cabinet design is NEMA, ventilated with gasketed doors. When requested, the cabinet ay also include interior lighting with switch convenience outlet, therostatically controlled space heaters, current liiting fuses for priary of power potential transforer and instruent potential transforers. ESS- EXCTATON SUPPORT SYSTEM When selective tripping of circuit breakers requires the generator to provide current under fault conditions, an excitation support syste can provide three phase current support and aid the starting of large otors. NEGATVE FELD FORCNG Refer to Basler product bulletin TBY for a description of our SSE-N, Negative Field Forcing Shunt Exciter/Regulator Syste. METERNG- AC and DC All eters are switchboard type with 1% accuracy and 27 dial scale. Metering ay include ac volteter, de field volteter, de field aeter, and Auto/Manual null eter for bupless transfer fro autoatic to anual voltage control. DODE FALURE DETECTOR When power seiconductor functional status is required, a onitor can be provided with the static excitation syste to annunciate when rectifier failure has occurred. VAR/POWER FACTOR CONTROLLER This device is used for parallel operation with the utility to regulate generator power factor or reactive power at a desired level without operator action. t is also used to aintain constant VARs or power factor on synchronous otor applications. AUTO TRACKNG MCROPROCESSOR-BASED REFERENCE ADJUSTER Used to adjust the anual voltage control for tracking the output of the autoatic voltage regulator. This option allows for bupless transfer when switching fro autoatic control to anual control. MCROPROCESSOR-BASED REFERENCE ADJUSTER Used to reotely control the regulation setpoint fro one or ore locations. PROTECTVE RELAYS A wide variety of protective relays can be included with the static excitation syste, including Field Ground Detection Relay, Voltage Phase Balance Relay, Underexcitation Relay with tie delay, Overexcitation Relay with tie delay, and Overvoltage Relay. AC SHUTDOWN and FELD FLASH CONTACTOR ASSEMBLY A contactor assebly can be supplied for all odels. The ac contactor reoves ac input 6 power to the exciter to shut down excitation. The contactor is controlled fro reote contacts. A field flashing contactor provides fast, positive voltage buildup fro a de battery reote fro the exciter. The field flashing circuit also includes an overflash protection circuit to autoatically interrupt the de source fro the field when the generator terinal voltage has not built up within 2 seconds. All 25Vdc SSEs rated up to 4 aps include Field Flashing and AC Shutdown contactors ounted on rectifier chassis. (Designed for 125Vdc battery. For operating voltages other than 125Vdc, consult the factory.) KLOWATS PER UNT Figure 6 - Miniu/Maxiu Excitation Liiting MNMUM/MAXMUM EXCTATON LMTER The excitation liiter perfors two functions when used with the SSE. As a axiu excitation liiter, it senses the field current output of the SSE and liits the field current to prevent overheating of the field. As a iniu excitation liiter, it senses the leading VARs into the generator and liits the excitation to prevent loss of synchronization and end-iron overheating during parallel operation. The liiter is adjustable to the achine's specific requireents. See Figure 6. OVER AND UNDER EXCTATON PROTECTVE RELAYS When positive generation syste shutdown is required due to exciter alfunction, the Basler Over/Under Excitation relays provide preprograed excitation liits to cause tripping of the shunt static exciter. POWER SYSTEM STABLZER When the power plant is subject to local or interarea ode oscillations, a Power Syste Stabilizer (PSS) can be provided. The PSS works through the suing point of the excitation syste to eliinate the low frequency power oscillations typically in the range of.2-3 Hertz. The PSS is a two input stabilizer (copensated frequency and power) that provides a conditioned signal into the excitation syste to odulate a braking torque on the rotor via the excitation syste to resolve the power oscillation.
