Air conditioner load monitoring system and method based on LABVIEW

Abstract

The invention discloses an air conditioner load monitoring system and method based on LABVIEW. The system comprises a monitoring center based on LABVIEW, and the monitoring center communicates with a plurality of monitoring terminals. Each monitoring terminal comprises a measurement instrument, wherein the measurement instrument is connected with a load terminal and used for monitoring the electrical load of the load terminal, the load terminal is controlled by an intelligent remote controller, and the measurement instrument and the intelligent remote controller communicate with the monitoring center through GPRS DTU. The monitoring center based on LABVIEW receives distribution network scheduling information, real-time frequency data of a microgrid are obtained, and a load terminal self-adaptive frequency change tracing response module is built according to the real-time frequency data of the microgrid; when the monitoring center finds that the frequency of the microgrid is reduced, in order to reduce the load frequency and balance the microgrid powder, the monitoring center sends a control instruction to the monitoring terminals, the temperature is adjusted to change instantaneous power requirements of the load terminals, and it is ensured that the temperature is adjusted to be always in the user comfort level range.

Problems solved by technology

[0007] The above research results are mainly applicable to the monitoring of household or building air-conditioning systems and central air-conditioning systems with a small number of air conditioners and a concentrated range. This aspect has not been considered, and it is impossible to realize the auxiliary participation of the load side in system frequency adjustment

The system established by "A Building Air Conditioning Equipment Load Monitoring System" can predict the power consumption information of the air conditioner load, and then adjust the load demand according to the scheduling information, and consider the user's power demand to a certain extent, but there are certain errors in the load forecast itself, and The response time for power demand adjustment based on load forecasting is long, and it is impossible to realize fast and accurate response of air-conditioning load to frequency changes and participate in system frequency adjustment
