Description

The invention relates to information. measurement and computing technology and can be used in the power industry to control the quality of transmitted electrical power consumed or consumed.

The purpose of the invention is to expand the functionality by taking into account the time factor of power consumption, improving speed and reliability in operation.

The drawing shows a functional diagram of the proposed analyzer-recorder.

The analyzer-recorder contains a current input 1 and a voltage input 2, a power-code converter 3 (RV voltage-code converter 4 (PNK), a first (matrix) multiplication module 5, a timer 6, a time-code converter 7 (PBC), the second (matrix) multiplication module 8, the counter 9 (adder) of the amount of electricity and the display unit 10.

PMK 3 information inputs connected to the inputs 1 and 2 of the analyzer-recorder. NCP 4 information inputs of the connections with the input 2 of the analyzer-recorder voltage, the first matrix module 5 multiplied by a group of first inputs is connected to the outputs of the PMK 3, and the group of second inputs is identical to the outputs of the NCP 4, the second matrix module 8 is multiplied by a group of first the bit inputs are connected to the outputs of the first multiplication matrix module 5, and the group of second inputs is bits through PVC 7 to the information outputs of timer 6, the first sync output of which is connected to the clock signals of the PMK Z. and PNK 4, the adder 9 is connected tional inputs porazr The battery 8 outputs the second modulation matrix multiplication, and clock terminal - with a second clock terminal timer 6, and information outputs - bitwise with the inputs of the unit 10 display.

Analyzer-recorder works as follows.

The current values of current I (t) and voltage and (t) of the transmitted supply or power consumed P (t) are fed in continuous analog form to the information inputs 1 and 2 of the analyzer-recorder, i.e. information inputs PMK 3 and PNK 4. At the outputs of the CMC 3, codes of the current values of the passing power P (t) are set (in discrete or digital form), and at the outputs of the PNK 4 - the current values of the quality factor codes K (U) (for example. K ,, - at voltage values falling in the field of nominal values; K, - K, - at voltage values falling

0 in the sampling field), the current time codes are set at the information outputs of timer 6, and the coefficient codes K, j (t) (for example, K ,, - K) corresponding to the time of day are provided at the outputs of PVC 7, at its first synchronous clock the presence of clocking pulses with a reference frequency in time, and at its second sync output - the presence of clocking pulses with the same frequency} but with a delay in T. The clock pulses of the first synchronization timer 6 synchronize the operation of converters 3 and 4, so that the codes

converters 3 and 4, respectively, are set with a delay T, and at the outputs of module 8 multiplication - with delay 2 due to the constant delays of modules 5 and 8.
