" TCP reads function " can be achieved the real-time monitoring to load data and data shown, stored,
" TCP writes function " can set up load with system frequency change directly in response to module simultaneously, and its response relation turns
Turn to LABVIEW language by wireless signal be sent to it is all monitoring loads terminals realize spatial load forecasting.
Finally realize the monitoring to cluster air conditioner load, complete air conditioner load participate in power system once, secondary frequency adjusts
Whole and on user comfort level requires that influence is minimum, and its Organization Chart is as shown in Figure 3.
(5) load responding traffic order participates in frequency modulation
1) guarantee of users'comfort
Because the heat exchange of air-conditioning work is continuation process, target temperature is adjusted in short-term can change its power demand but room
Interior temperature change is smaller, smaller on users'comfort and usability influence, therefore can be adjusted by changing cluster load target temperature
Its whole power demand, it is ensured that response scheduling demand while users'comfort.
2) foundation of load-frequency respond module
Through research, air conditioner load target temperature typically obeys discrete Gaussian Profile, independently of one another, can be according to micro-capacitance sensor frequency
Change each respond, adjust to change cluster load power demand, auxiliary power generation on the basis of initial target temperature setting value
Side maintains system frequency stable.It is illustrated in figure 4 the target temperature setting value of air conditioner load and micro-capacitance sensor frequency under each refrigerating state
Rate variation relation, when micro-capacitance sensor frequency declines, cluster load target temperature is linearly raised in its initial set value, frequency rise
When then target temperature value decline.The quantitative relationship such as formula (1) that target temperature changes with micro-capacitance sensor frequency is shown.
