Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front", "rear", "both ends", "one end", "the other end", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, such as "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, the present invention provides an intelligent control system for electrical optimization, including: the intelligent control system comprises data acquisition equipment 1, an intelligent control center 2, a communication unit 3 and a power control terminal 4; one end of the data acquisition equipment 1 is connected with corresponding power equipment or a transmission line, and the other end of the data acquisition equipment is connected with the intelligent control center 2 through the communication unit 3; the intelligent control center 3 is connected with the power control terminal 4.
The data acquisition equipment 1 may include a voltage and current measuring instrument, a monitoring probe, a relay protection device, and a wave recorder connected to an electric device or a transmission line. For example, a transformer in a district or a factory monitors the voltage and the current of the transformer, and is convenient for the adjustment and the control of an intelligent control center. And reasonable optimization suggestions can be given according to the use condition of the transformer. Specifically, an appropriate transformer bank is selected according to actual conditions, and the transformer is divided into a single-phase transformer and a three-phase transformer according to the number of phases. In the process of single-phase load, the single-phase transformer can be applied to achieve the target, and in this case, the transformer set is installed, so that the transformer consumes certain power resources, unnecessary power resource consumption occurs in the using process of the transformer, and the target of electric energy conservation and emission reduction is not met. Therefore, in the construction process, in order to effectively realize the energy conservation and emission reduction of electricity, the transformer needs to be scientifically and reasonably selected according to actual conditions.
The monitoring probe is used for acquiring the running states of the power equipment and the lines in the monitored area, and generating and displaying pictures. For example, the power supply distance in the monitoring area can be identified by the existing image identification technology, and a picture record is generated for the operation state of the power supply equipment. The intelligent control center ensures that correct judgment can be realized in voltage selection through the determination of the power supply distance and the operation state, so that the aims of electrical energy conservation and emission reduction are fulfilled, and unnecessary consumption of power resources is reduced or lowered. Such as unnecessary bending, rotation, etc. of the wires laid in the monitoring area; the intelligent control center can give a new routing strategy to reduce the bending or turning.
The relay protection device can act on a breaker to trip or send a signal when a fault or abnormal operation state occurs to electric equipment such as a generator, a circuit, a transformer, a capacitor, a motor and the like of an electric element in a power system. When the fault occurs, the fault element is automatically, rapidly and selectively cut off, so that the fault element is prevented from being continuously damaged, and other parts without the fault are ensured to rapidly recover to normal operation. In addition, a fault signal (trip or load shedding) can be sent to the intelligent control center. The intelligent control center can analyze and process the signals and send corresponding processing strategies to the power control terminal. When a short circuit is transmitted, overcurrent protection, low-voltage protection, and distance protection are performed using current, voltage, line measurement impedance, and the like.
The wave recorder functions: when the power system has faults and oscillation, automatically recording the fault type, the fault occurrence time, the current and voltage change process and the action conditions of the relay protection and the automatic device, and calculating the distance from a short-circuit point to the installation position of the device; the information is sent to an intelligent control center for analysis and processing by the intelligent control center, and a fault trend is sent to the future power system to give an early warning or remind of processing faults and give a fault solution in combination with historical data.
For example, taking a transformer as an example, after obtaining voltage, current value, and internal temperature value of the transformer, the electrical quantity protection that can be performed for a fault of the transformer is specifically configured as follows:
differential protection, high-side backup protection (including composite voltage start overcurrent protection, zero-sequence current protection, etc.), low-side backup protection (including composite voltage start overcurrent protection, overload protection, etc.)
The non-power protection configuration that can be performed is as follows:
the gas protection is one of main transformer main protection, including main transformer body and on-load tap changer, and light gas action signals, and heavy gas action jumps the main transformer both sides circuit breaker instantaneously. The main transformer pressure release protection instantly jumps circuit breakers on the two sides of the main transformer.
And temperature protection, namely, the circuit breakers at the two sides of the main transformer are tripped by action when the temperature is too high, and the circuit breakers act for signaling when the temperature rises.
In this embodiment, the data acquisition device is configured to acquire operation data of a corresponding power device or transmission line; transmitting the operation data to the intelligent control center through a communication unit; the intelligent control center carries out analysis processing and converts the analysis processing result into an optimization instruction; and sending the optimization instruction to the power supply control terminal, and executing corresponding actions by the power supply control terminal to realize the optimal configuration of the electric circuit. The invention realizes the automatic monitoring, measurement, automatic control and microcomputer protection of the power transmission and distribution lines of the transformer substation, the transmission line and the electric equipment and the comprehensive automatic functions of communication with dispatching and the like by combining and optimally designing functions and utilizing advanced data acquisition equipment, computer technology, communication technology and signal processing technology. The monitoring and the operation of the normal operation of a transformer substation, a transmission line and electric equipment can be realized, the collection, the monitoring and the control of transient electric quantity are finished by relay protection, fault recording and the like when an accident occurs, the fault is quickly removed, and the recovery operation after the accident is finished; and reasonable optimization is carried out, and normal operation and safety are ensured.
