Problems solved by technology
However, when the voltage is significantly lower than the rated value, the reactive power demand of the air-conditioning load will increase with the voltage drop, which will exacerbate the tension between reactive power supply and demand in the power grid, and increase the risk of voltage collapse in the power grid

Embodiment Construction
[0021] The invention detects the real-time frequency and voltage of the power grid through a dedicated frequency / voltage detection chip, analyzes the real-time operation status of the power grid according to the measured data, queries the control strategy table, sends out response signals according to the corresponding control strategy, and independently executes the response instructions.
[0022] Such as figure 1 Shown: The air conditioning intelligent adjustment device of the present invention based on the user's active safety response obtains the grid real-time frequency and voltage information from the AC grid through the frequency / voltage detection module, and then transmits the data to the central processing unit for data analysis. According to the analysis result, query the control strategy table. Then send a response action signal to the control module according to the corresponding strategy, and the control module will act after receiving the command to complete the resp...

The invention applies in electric field, and provides an intelligent air-conditioner adjusting device based on active security response of a user, which comprises a frequency detection module, a voltage detection module, a central processing module and a response control module. The frequency detection module and the voltage detection module adopt a special frequency / voltage measurement chip for real-time measurement of the frequency and voltage of a power grid. The central processing module is provided with a built-in control strategy table fabricated according to historical data of the power grid, and is used for judging the real-time operation of the power grid via analyzing the actually measured frequency / voltage data of the power grid, inquiring the control strategy table, adjusting the power and parameters according to the strategy table, and sending response signals. The response control module is used for sending response commands after receiving the response signals and adjusting the operating parameters of an air-conditioner in a short time (a plurality of seconds to a plurality of minutes). By adopting the device, the active security response of the load can be realized while the power consumption of the user is not affected, and the capability of the power grid to maintain safe and stable operation can be improved.
Description
Technical field [0001] The present invention relates to the electrical field, and in particular, to an air conditioner intelligent adjusting device based on a user's active safety response. Background technique [0002] 1. Demand response [0003] Demand response is a short-term load response behavior and market mechanism developed on the basis of power demand side management. It refers to users in normal consumption patterns, according to changes in market electricity prices or through incentive compensation mechanisms to reduce peak power demand or in system reliability React when threatened. By changing its inherent power consumption mode, the wholesale power market is price elastic, thereby reducing peak power load, improving system reliability, reducing the overall cost of the system, improving market efficiency, and preventing market members from manipulating the market and allowing market participants to avoid Risk of system security and price fluctuations. In addition, t...
