Definitions

  • a method for operating an electronic electricity meter having current and voltage sensors configured to generate measurements of current and voltage, respectively; a microcomputer coupled to the current and voltage sensors and having on-chip masked read only memory (ROM); and a nonvolatile, alterable memory coupled to the microcomputer.
  • the method includes steps of: storing vectors pointing to program portions of the ROM in the non-volatile memory; and using the stored vectors to operate the microcomputer to execute the program portions stored in the
  • the above-described embodiment provides a method for inexpensively upgrading an electronic electricity meter.
  • Figure 6 is a mode diagram for a complex I/O board. DETAILED DESCRIPTION OF THE INVENTION
  • User-selected quantities 230 specified by measurement profile 204 can be used to perform totalization. For example, a value from a register location in user- selected quantities 230 (e.g., register 7) can be added to a value stored in a register location (e.g., register 17) to provide a totalized value, and the totalized value is stored in a register location (e.g., register 17). In the embodiment illustrated in Figure 2, up to 8 totalizations can be performed.
  • min and max values may be voltage, frequency, current, etc.
  • each board type has an identifier.
  • a 3 -bit address specifies the board type.
  • an input/output board is specified as a type 001.
  • a logic 0 on all response lines means no option board of the specified type is present.
  • a simple I/O board 136 has an identifier of 01.
  • a complex I/O board 138 has an identifier of 10.
  • Microcomputer 114 is programmable to determine energy consumption and other metering quantities for many different form types. In addition, and if one phase voltage is lost during metering operations and the other two phase voltages are still available, microcomputer 114 automatically converts from a three voltage source metering operation to a two voltage source metering operation. For example, and if metering is being performed with three input voltage sources V a , Vj,, and V c , and if one of the phase voltages, e.g., V a , is lost, microcomputer 114 automatically changes to metering to the appropriate form type, i.e., generating metering quantities using V b and V c .
  • a diagnostic 5 error condition is triggered if any of the distortion calculations exceed a user-specified threshold.
  • an operator can specify that upon the occurrence of a maximum demand, two coincident power factor values are stored, e.g., Demand 1 / Demand 2 and Demand 3 / Demand 4.
  • the demand with timekeeping mode (sometimes referred to in the art as the demand with timekeeping mode), and the TOU mode.

Abstract

Dans un mode de réalisation, la présente invention concerne un procédé permettant de faire fonctionner un compteur d'électricité électronique (100) comportant des capteurs de courant (104) et de tension (106) conçus pour générer des mesures de courant et de tension, respectivement, un microordinateur (114) relié aux capteurs de courant (104) et de tension (106) et présentant sur sa puce de la mémoire morte (ROM) (120) masquée, et une mémoire non volatile, altérable (118) reliée au microordinateur (114). Le procédé consiste : à stocker les vecteurs montrant les parties de programme de la mémoire ROM dans la mémoire non volatile, et à utiliser les vecteurs stockés pour actionner le microordinateur de sorte qu'il exécute les parties de programme stockées dans la mémoire ROM pour commander les opérations du compteur (100).
