AUTOMATIC POWER MEASUREMENT EQUIPMENT CONNECTED TO INTELLIGENT NETWORK OF DIRECT ELECTRIC HEATING
Abstract:

When using electric heating it is necessary to limit the maximum power of the connected load. Therefore, the heating system is controlled using smart connectors (smartсones). They determine who will turn on the heaters at each specific moment in time, so that the total load does not exceed the established limit depending on the temperature in the premises. For this we need to know which load is connected to each smartcon and the type of load. Only the connectors to which the heaters are connected are used in distributed energy.

For the recognition of the nature of the load parallel to the key switching is enabled, the additional resistance to measure reactive power at low current load. If a heating device is connected, its reactive power is sufficiently small. If a computer, a refrigerator or some electromechanical device is connected, its reactive power is much higher. When the lighting device is connected, its reactive power is low, but the active power is less than that of the electric heating device. This creates a problem of the inaccuracies to non-simultaneous instantaneous measurements of currents and voltages. To avoid the inaccuracy proposes method of double scanning.
