Description
Technical field
The utility model relates to power automation control field, relates in particular to generator load self-adaptive regulating in the power plant for self-supply.
Background technology
In industrial and mining enterprises such as cement, petrochemical industry, iron and steel, its power consumption is bigger, if fully by the external electrical network power supply, can increase the production cost of enterprise, so tend to set up the private station power supply in enterprise, reduces outside to reach the purpose of saving cost.In actual applications, enterprise usually can still incorporate external electrical network the same period into when setting up private station: when private station can not satisfy the needs of enterprise's production and operation, by the external electrical network supplementary power; When the private station energy output surpasses needing of enterprise's production and operation, treaty conditions according to each enterprise and power department signing, the super electric weight that send of some regulation must be free, if some stipulates that then the super electric weight that send surpasses behind certain numerical value then the electrical network of forcing to provide for oneself electrical network and power department separates, all be disadvantageous no matter be that a kind of mode to this enterprise this moment.So enterprise can regulate the power output of self-built generating set in real time according to the need for electricity of this enterprise, by increasing or reduce the power output of self-built generating set, reach the self-balancing state, not only satisfy the demand of this business electrical amount but also the purpose that can further save cost to reach.
At present in the self-built power plant of enterprise, the manual adjustments mode is still adopted in the control of its generating set power output, the actual consumption electric weight of the production and operation by manual record and more self-built generating set energy output and enterprise carries out next step action: when the power output of energy output increasing generator during less than the actual consumption electric weight, in the time of still can't satisfying the power consumption of this enterprise when power output transfers to maximum, insufficient section is provided by outer net; When energy output reduces the power output of generator during greater than the actual consumption electric weight.There are some problems in this regulative mode: at first can increase staff's labour intensity, and increase human cost; Secondly, because the need for electricity of this enterprise is transient change, rely on operating personnel to regulate fully, regulating action can lag behind, and does not reach the purpose of real-time adjusting, and manual adjustments numerical value is not accurate yet, in practical operation, for the preferential needs that guarantee enterprise production and management, operating personnel tend to reduce the energy output of self-supply power plant, absorb certain electric weight from external power grid and guarantee operation, wasted the resource of self-supply power plant like this.
Summary of the invention
The utility model aims to provide a kind of generator load self-adaptive regulating, thereby makes generator load can realize that the self adaptation adjusting reaches the purpose of saving cost.
A kind of generator load self-adaptive regulating described in the utility model comprises:
Net side power detector is installed between enterprise's electrical network and the external electrical network, for detection of the power direction between enterprise's electrical network and external electrical network and size;
The output of a generator detector is installed between generator and the enterprise's electrical network, for detection of the power output of generator;
Analog input unit connects net side power detector and output of a generator detector, reads the detection numerical value of net side power detector and output of a generator detector, and the numerical value that detects is flowed to processor;
Processor connects analog input unit, numerical value and the set point of analog input unit input is compared, and form corresponding control command according to comparative result and flow to the digital quantity input unit;
The digital quantity output unit connects processor, and control command is transmitted to the generator load controller;
And the generator load controller, according to the rotating speed of control command control generator, thus the power output of control generator.
A kind of generator load self-adaptive regulating described in the utility model, set when enterprise's electrical network during to outside mains supply, the numerical value that net side power detector records is for just, when external electrical network during to enterprise's mains supply, the numerical value that net side power detector records is for negative, set when generator during to enterprise's mains supply, the numerical value that the generator power detector records is for just.At this moment, if the numerical value that net side power detector detects is for just and greater than set point the time, processor sends control command, reduces by generator load controller control generator speed, and is excessive to avoid externally powering reducing the generated output of motor, causes waste; If the numerical value that net side power detector records is for negative, and the numerical value that output of a generator detects is during less than the maximum power value of generator, processor sends control command, increase by generator load controller control generator speed, to increase the generated output of motor, to reduce the power supply of external electrical network, save cost.
For protective circuit and equipment; connect the generator outlet circuit breaker between generator and the enterprise's electrical network, when serious overload, short circuit, fault such as under-voltage appearred in circuit, the generator outlet circuit breaker can automatic disconnection; cut off circuit, thereby reach the purpose of protective circuit and equipment.After the generator outlet circuit breaker disconnects, generator is not carried electric weight to enterprise's electrical network, if the generator load self-adaptive regulating works on, can judge that the power output of generator is too small, can send instruction control generator and increase power output until maximum power, cause unnecessary waste.Solution is as follows: the generator load self-adaptive regulating also comprises the digital quantity input unit, the digital quantity input unit connects generator outlet circuit breaker and processor, the digital quantity input unit reads generator outlet breaker closing state or off-state signal, and this signal transferred to processor, this moment, processor was if receive then generator load self-adaptive regulating operate as normal of generator outlet breaker closing status signal, if receive generator outlet circuit breaker cut-off signal then the generator load self-adaptive regulating quit work, saved cost.
