Operation of a long-term transient monitoring system in a 138-KV and a 500-KV substation  

SciTech Connect

This paper describes the operating performance of automatic transient monitoring laboratories designed to capture fault and transient data on power systems. Laboratories were installed in a 138-kV and a 500-kV substation and operated for more than 25,000 hours over a three-year period. Recorded during this period were 341 events consisting of lightning, switching, and fault transients. These results provide invaluable data on actual transients in power systems to aid power system equipment designers.

Retrofit of an existing 160 MVA 69KV major Chicago downtown substation to 200 MVA 138KV while maintaining continuity of service  

SciTech Connect

In 1957 Transmission Substation 68, LaSalle, (TSS 68) was placed in service. This paper reports that the station consists of four 40 MVA 69 kV/12 kV transformers which feed two 12 kV ring buses. The 12 kV switchgear is housed on the first and second floors of a 62 year old structurally sound building. Located on the south and west sides of this building are the four transformers. The entire station is located on a parcel of land approximately 14,000 square feet.

Functional design criteria exploratory shaft power line and substation Project B-417  

SciTech Connect

This project will provide a 13.8-KV, 3-phase electrical power line from substation B-251 to the ES site. The power line will be sized to carry the 6000 KVA power required to meet the construction and operations power requirements of the facility. The line will originate at an existing circuit breaker at the 13.8 KV switch gear at substation B-251 and will terminate at fused cutouts at the ES site. Wood poles will be used for the aerial support of the {approximately}4.7 mile transmission line. Joint use of the line by project B-316 is being considered. The substation will provide transformation from 13.8 KV to 2.4 KV, transformer mounting, grounding grid for the entire substation, the substation fence, and connection between the primary side of the transformer and the 13.8 KV electrical line (last pole) provided by Part 1. Switching stations, protective devices, and metering, which are normally part of a substation, will be provided by the ES Project, B-314. 10 refs.

Spectrum analysis of the power line flicker induced by the electrical test of the prototype Booster dipole  

Science Conference Proceedings (OSTI)

Testing of the prototype Booster dipole magnet at full current produced measurable disturbances of the beam position at the National Synchrotron Light Source. Power for the magnet and the NSLS are distributed from three substation transformers at Temple Place. Normally the substation configuration is for two independent 13.8 KV buses, derived from the 69 KV LILCO distribution. The buses are connected through a circuit breaker that is normally open circuited. Power for the magnet test is derived from one of the 13.8 KV buses and power for the NSLS is derived from the second bus. Coupling of the pulsating magnet load and the NSLS is at the 69 KV level. However, on the days that the interference was first observed at the NSLS only one-half of the substation transformers at Temple Place were in service. The 13.8 KV tie breaker was closed and the full substation load was supplied from this common bus. Thus the coupling between the pulsating magnet load and the NSLS was at the 13.8 KV level. Establishing the normal two bus configurations at Temple Place appeared to reduce the disturbance. These events suggested a controlled experiment to measure the magnet power swing and the induced powerline flicker; and from these measurements project the flicker on the lab site generated by the Booster operating at full energy. This experiment could corroborate the validity of the electrical models used in analyzing the power flow from the LILCO power grid and its distribution on the Lab site described in Accelerator Division Technical Note 220.

100-N temporary construction line considerations  

SciTech Connect

Present thinking and planning appears to be developing from the following factors as concern the 13.8 KV temporary construction power limit. 1. It is understood that the present intent is to supply 100-N operating requirements from a single stub source in the 230 KV loop. 2. The original thoughts were to obtain construction power over a 13.8 KV line from 151-D substation. 3. Construction load requirements are now less than originally planned since steam has been substituted for electrical drive of primary loop pumps and 5500 hp motor tests are no longer necessary. 4. An extreme emergency backup source for the K plants has always been of concern, although minimized in recent planning. It is desirable to review the temporary construction line requirements from a future operating viewpoint to determine if the line could be useful to the operating plants after completion of construction. It is highly desirable to provide T.C. power source from K plants rather than 151-D and then leave the line and breakers in place for future maintenance assistance and as extreme emergency backup to K plants.

Effect of increased electric loads on primary substation equipment in 100-B, C, D, DR, F, and H areas  

SciTech Connect

The loading on the primary transformers which step down the 230 kv transmission voltage to a distribution voltage of 13.8 kv, at 100-B-C, 100-D-DR, 100-F, and 100-H Areas will be increased by the synchronous motors now being installed in those areas under Project CG-558. This report summarizes: The changes in electric loads (both kv and power factor) which will result when the new motors are placed in service and certain older motors are withdrawn from service. Electric loads are tabulated in section 4.0 for each area for present conditions, the planned changes and the post-CG-558 conditions. The reduction of distribution voltage during the starting of individual 4500 hp synchronous motors. Since the synchronous motors will be started across the line as induction motors, the starting current will be high, and at a low power factor. Voltage drops are calculated for the starting of a synchronous motor, with one and then with two transformer banks paralleled. The current-interrupting capacity of switchgear vs. the maximum short-circuit current which could occur with separate transformers and with two primary transformers in parallel.

SIMULATION RESULTS OF RUNNING THE AGS MMPS, BY STORING ENERGY IN CAPACITOR BANKS.  

SciTech Connect

The Brookhaven AGS is a strong focusing accelerator which is used to accelerate protons and various heavy ion species to equivalent maximum proton energy of 29 GeV. The AGS Main Magnet Power Supply (MMPS) is a thyristor control supply rated at 5500 Amps, +/-go00 Volts. The peak magnet power is 49.5 Mwatts. The power supply is fed from a motor/generator manufactured by Siemens. The motor is rated at 9 MW, input voltage 3 phase 13.8 KV 60 Hz. The generator is rated at 50 MVA its output voltage is 3 phase 7500 Volts. Thus the peak power requirements come from the stored energy in the rotor of the motor/generator. The rotor changes speed by about +/-2.5% of its nominal speed of 1200 Revolutions per Minute. The reason the power supply is powered by the Generator is that the local power company (LIPA) can not sustain power swings of +/- 50 MW in 0.5 sec if the power supply were to be interfaced directly with the AC lines. The Motor Generator is about 45 years old and Siemens is not manufacturing similar machines in the future. As a result we are looking at different ways of storing energy and being able to utilize it for our application. This paper will present simulations of a power supply where energy is stored in capacitor banks. The simulation program used is called PSIM Version 6.1. The control system of the power supply will also be presented. The average power from LIPA into the power supply will be kept constant during the pulsing of the magnets at +/-50 MW. The reactive power will also be kept constant below 1.5 MVAR. Waveforms will be presented.
