Description
Technical field
The present invention relates to electric field, in particular to a kind of air conditioner intelligent adjusting device based on the response of user's active safety.
Background technology
One, demand response
Demand response is short term respondent behavior and the market mechanism growing up on the basis of demand Side Management, it refers to that user is under normal consumption pattern, changes or is reduced peak power demand or reacted in the time that system reliability is on the hazard by excitation remuneration mechanism according to market electricity price.Intrinsic with power mode by changing it, make wholesale electricity market there is price elasticity, thereby minimizing peak load, the reliability of raising system, the holistic cost of reduction system, improve market efficiency, and prevent that market member from rigging the market, and makes the risk of participant in the market's avoidance system safety and price fluctuation.In addition, utilize demand response to move peak, can reduce the spare capacity that the operation of conventional electric power system needs, reduce the pressure of safeguarding electrical network reliability service.
Two, interruptible load
Sub-load in power system is not too high to the requirement of power supply reliability, under certain economic compensation or reparation condition, can tolerate small probability power outage, as interruptible load (Interruptible Load, IL).By the compensation way to user, after interruptible load is divided into have a power failure front low electricity price compensation and power failure, high electricity price is compensated 2 classes.Be to compensate by contract after family is accepted discount electricity price compensation that power failure probability exchanges for and had a power failure in reality.The former is corresponding to daily low-cost, and as paying Generation Side capacity payment for subsequent use, whether reality occurs irrelevant with power failure; The latter is corresponding to the high cost of small probability, and take only just payment after reality power failure as paying Generation Side electric weight for subsequent use.
Three, the impact of air conditioner load on China's electrical network
Along with the high speed development of national economy and improving constantly of living standards of the people, various air-conditioning systems are widely applied.According to measuring and calculating, the air conditioner load of some big and medium-sized cities of China has accounted for the more than 30% of summer Largest Load, and certain areas have even exceeded 50%, and this quantity also will present rapid growth situation in the coming years.Affected by air conditioner load, each electrical network power load in summer increases rapidly, and peak-valley difference further widens, and the sharp increase of air conditioner load has become network load characteristic degradation and power supply and demand major reason in short supply in summer.
In recent years, the result of study that air conditioner load is carried out shows more consistently: air conditioner load proportion increases, and the starting characteristic that it is special and voltage recovery characteristics will produce more and more adverse influence to the voltage stability of electrical network.If System Reactive Power power supply deficiency, can make the reactive power equilibrium of electrical network in low voltage level, i.e. the minimizing of logical superpotential reduction, load absorption reactive power makes up the deficiency of reactive power source.But in the time that voltage is starkly lower than rated value, the reactive requirement of air conditioner load has rising on the contrary with voltage drop, the nervous situation of the idle supply and demand of aggravation electrical network, increases the danger of electrical network generation collapse of voltage.Once there is once thrilling collapse of voltage accident in Tokyo in July, 1987, and air conditioner load plays very large negative effect in accident.
Therefore, must pay much attention to the impact of air conditioner load on power grid security, stable, economical operation, actively utilize economy, administration and the technological means such as demand management, the response of user's active safety, realize effective management of air conditioner load.
Four, user's active safety response
For meeting the instantaneous equilibrium of supply and demand requirement of power system, research in the past is always considered from the side of exerting oneself, is adjusted generated output and power transmission and transforming equipment according to electric load situation of change.As the extension of existing interruptible load and demand response research, from load side, user or consumer are according to electrical network real time execution situation, as voltage, frequency etc., in conjunction with electrical network real time price information, the electricity consumption behavior of active accommodation oneself, control self load switching situation, carry out peak load cutting or use electricity in off-peak hours, realizing economic electricity consumption, assisting to safeguard the safe and stable operation of electrical network.Improving stability and the economy of power system by the active accommodation of user or consumer, is one of effective means ensureing the effective stable operation of power system security.In order to evade the adverse effect of air conditioner load to electrical network, this patent, based on above-mentioned achievement in research, is invented a kind of air conditioner intelligent adjusting device based on the response of user's active safety.
Summary of the invention
The present invention is intended to invent a kind of air conditioner intelligent adjusting device based on the response of user's active safety.The embedded response control strategy of this device table, by analyzing the mains frequency and the voltage change that detect in real time, judges electrical network real time execution situation, adjusts electric power and parameter according to Policy Table.In the time that mains frequency or variation reach a provisioning response threshold, to experience as prerequisite not affect user power utilization, short-term correction air conditioner operation parameters, improves the ability that electrical network keeps balance.
The present invention is divided into frequency detection module, voltage detection module, central processing module, response module.
Frequency/voltage detection module adopts dedicated frequency/voltage measurement chip, detects mains frequency/voltage one time second, and transfer data to central processing module every t.
Central processing module embeds the control strategy table of formulating according to electrical network historical data, the degree that in this Policy Table, mains frequency is departed to its rated value is divided into m grade, the degree of its rated value of voltage deviation is divided into n grade, under different response thresholds, formulate different response policies, response control strategy is divided into (m+n) level.Response threshold value arranges the particular attribute such as starting characteristic, locked rotor characteristic of simultaneously considering air-conditioning self.The measured data that central processing module receive frequency and voltage detection module transmit is also carried out total score and is analysed, and then inquires about control strategy table, according to corresponding strategy, adjusts electric power and parameter.Adjust parameter and comprise thermoregulator end value (improving or reduce T degree on the basis of current surveyed indoor temperature) and duration length thereof.
Response module is sent parameter adjustment order by infrared learning module after receiving the response signal that central processing module sends, and stops the testing process of frequency and voltage detection module simultaneously.Reaching after default response actuation time, stop response process, send response termination signal by response module, central processing module is received the normal operation that recovers frequency/voltage detection module after signal.
Because the adjustable range of adjustable parameter is little, therefore can realize in the situation that not affecting user power utilization experience, short-term correction load, to improve the ability of electrical network maintenance balance.In addition, human-computer interaction interface of the present invention carry out air conditioner load can the current air-conditioning design temperature of simultaneous display while adjusting in short-term, the real-time status parameter such as room temperature, for user's inquiry.
