Definitions

  • All the equipment, especially the voltage divider, is mounted in a standard container, which is coupled with an autonomous lifting system which facilitates its transport as well as its easy placement in the vicinity of the electric generator, without the need for cranes auxiliaries
  • the probes are composed of voltage probes based on voltage-to-voltage Hall effect transducers that measure the voltage instantaneously with a sample rate of at least 100,000 samples / second and 16 bits of resolution and based current probes in Rogowski type current-to-voltage transducers that measure the alternating current instantaneously with a sampling frequency of at least 100,000 samples / second and 16 bits of resolution. All probes are monitored by the divider control equipment.
  • the first (XI) and last (X6) inductance have the same value; the value of the second (X2) and fifth (X5) inductance is the same and corresponds to 4 times the impedance of the first (XI) and last inductance (X6); the third (X3) and fourth (X4) inductance has a value of 8 times the value of XI and X6.
  • Isolated three phase balanced surges They are overvoltages where the three phases have the same value in amplitude and the phase angle does not change, or single-phase overvoltages to ground. They are overvoltages in which one of the phase voltages suffer changes in its amplitude but not in its phase angle, being able to choose between the combination of phases AN, BN or CN.
  • Biphasic ground overvoltages They are overvoltages in which two of the phase voltages undergo changes in their amplitude but not in their phase angle, being able to choose between the combination of phases AB, AC or BC.
  • Figure 3 shows a device variable consisting of the inductive divider coupled with a bank of capacitors and another bank of resistors.
  • Figures 14 and 15 show two perspectives of the container that houses the divider.
  • the control equipment (2) connects with the input of the electric generator in its three phases through three probes (35) for voltage measurement and low voltage current that measure the voltage and electric current suffered by the electric generator when on the electrical network (1) the divider (34) performs a disturbance defined by the user.
  • These probes (35) collect the voltage and current data which are sent to the control equipment (2) to perform the analysis of the disturbances that are made in the network (1) as well as their storage in a physical memory type SSD which will serve to subsequently perform the analysis of the behavior of the electric generator as a function of the received disturbance.
  • the control device (2) also connects to the output of the electrical network (1) with the help of three probes (36) of voltage and current in low voltage that connect with each phase of the network (1) .
  • the team monitors the changes that the electrical network undergoes before its arrival at the divider (34) and with this data modifications will be made in the configuration of the divider (34) to adapt the conditions of the network (1) to the disturbance that you want to perform.
  • the data collected by the probes (36) are stored in physical memories such as the SSD type not shown in the figures.
  • the switches (24, 25 and 26) connect in a three-phase manner with the phase switch (27) that connects with the neutral of the network (1).
  • the three switches (24, 25 and 26) are in parallel.
  • the type of hole is selected as explained above.
  • the switch (17) will open, if necessary, to perform the hole maneuver, switch operation (23) will be enabled, the gap being made and the equipment returned to the by-pass state by closing the switch ( 17) waiting for another hole or configuration change to be made.
  • the set of the two transformers (40, 43) makes it possible to adjust the input and output voltage levels of the divider (34) and thus establish the conditions of the disturbance suffered by the generator (3), with the transformer (40) which reduces the voltage of medium or high voltage to 690 V.
  • the transformer (43) raises the voltage of 690 V to the level of medium or high voltage in the network and also through the switches (41) and (42) can be configure the two-phase type C holes when the connection is star, with switch (41) closed, or two-phase holes type D when the connection is in a triangle, switch (42) closed.

Abstract

La présente invention concerne un dispositif conçu pour générer des perturbations de réseau au niveau d'un générateur, comprenant un diviseur de tension inductif (34) qui comporte un équipement de commande (2), un support de 6 inductances (28 à 33), reliées entre elles par une matrice de 18 sectionneurs (5 à 22) et 5 interrupteurs (23 à 27) accouplés. Il est possible de raccorder au diviseur (34) : • un ensemble de transformateurs (40, 43) • un banc de condensateurs et de résistances (75), • un module de surtension (OVRT, 79). Ce dispositif permet de réaliser des essais pour des puissances du générateur (3) comprises entre 0 kW et 8.000 kW. L'essai de surtension est réalisé en faisant passer un courant de court-circuit par les bobines (77) accouplées aux bobines (78), ce qui résulte en 403 configurations différentes et produit 2.821 surtensions différentes de par les combinaisons des inductances (28 à 33), des sectionneurs (5 à 16) et (17 à 22) et des interrupteurs (24 à 27).
