Abstract
The utility model discloses a real-time line loss monitoring and analyzing system based on a PI (Processing Instruction) for a power distribution line, and the system a transformer monitoring terminal, a GPRS (General Packet Radio Service) communication network, a master station server and a database, wherein the transformer monitoring terminal collects public-transformation and special-transformation electric quantity of the power distribution line; electric quantity data is transmitted to the master station server through the GPRS communication network; and the master station server switches data into the database. The real-time line loss monitoring and analyzing system based on the PI for the power distribution line has the advantages of short newly-counted period, low cost and accurate counting result; through establishing the system, the power grid loss is reduced in the design of a power distribution network in the future, so that a data analysis basis is provided. The public-transformation and special-transformation relevant electric quantity of a power distribution line device is collected by the transformer monitoring terminal and a GPRS data transmission service of the power distribution line device is utilized to switch real-time data of a power supply side and a power use side into a PI database and count the line loss condition of the PI database. The line loss counting method has the advantages that the counting efficiency is high, the cost is low, and the counted result is the same as the actual line loss.
Description
Technical field
The utility model relates to based on the real-time line loss monitoring and analyzing system of the distribution line of PI.
Background technology
Line loss is a mixed economy technical indicator of power supply enterprise, relates to power planning, design, capital construction, renovates, numerous aspects such as operation maintenance, maintenance, metering, management.The factor that influences the line loss variation is intricate, has both reflected the technology management level of power supply enterprise, has embodied the management level of enterprise again.After electric network reconstruction, grid structure is several to be tending towards rationally, and the configuration of electrical network layout, public change, line powering radius and conductor cross-section are selected all to have obtained very big improvement, have reduced line loss technically effectively.But some aspect is still perfect not to the utmost, and line loss is gone up and down repeatedly.
1, the electrical network three-phase load distributes inequality, causes that neutral current increases, and causes loss to increase.
2, the low-voltage circuit reactive-load compensation is not enough, causes power factor (PF) generally lower.
3, fail the choose reasonable substation transformer in the design, load growth is slow, and distribution transformer capacity is excessive, causes circuit underloading or zero load, and loss is high.
Traditional line loss statistical method mainly contains two kinds:
1, checks meter statistical computation more by hand.The line loss value angle that this statistics line loss method draws is accurate, but the cycle of statistics is long, adds up loaded down with trivial details, and cost is high.
2, set up mathematical model according to the main losser of network, adopt average current method and rms current method to calculate.This line loss method statistic is convenient, but error is bigger, and line loss of calculating and actual line loss differ far away.
The utility model content
The purpose of the utility model is to provide based on the real-time line loss monitoring and analyzing system of the distribution line of PI; The electrical equipment that can solve existing underground distribution room effectively is positioned the decreasing insulating that the running environment rugged surroundings very easily cause electrical equipment, influences the problem of the safe and stable operation of electrical equipment.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
Based on the real-time line loss monitoring and analyzing system of the distribution line of PI; It is characterized in that: comprise Distribution Transformer Terminal Unit, GPRS communication network, main website server and database; Distribution Transformer Terminal Unit is gathered the public electric parameters that becomes and specially become of distribution line; Through the GPRS communication network electrical data is sent to the main website server, the main website server inserts database with data.
The utility model has following beneficial effect owing to adopted technique scheme:
The cycle of statistics is short, and cost is low, and statistics is accurate; And the foundation of this system, to distribution network design from now on, reducing grid loss provides the data analysis foundation.Adopt the Distribution Transformer Terminal Unit device to gather the public change of distribution line, the special covert electric parameters of closing; Utilize the GPRS data transmission service of Distribution Transformer Terminal Unit device; The real time data of supply side and electricity consumption side is inserted the PI database, and in PI statistics of database line loss situation, this line loss statistical method statistical efficiency is high, cost is low; The result of statistics is consistent with actual line loss, is the line loss statistical project of present domestic the best.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the block diagram of the utility model based on the real-time line loss monitoring and analyzing system of distribution line of PI.
Embodiment
As shown in Figure 1; For the utility model based on the real-time line loss monitoring and analyzing system of the distribution line of PI; Comprise Distribution Transformer Terminal Unit, GPRS communication network, main website server and PI database, Distribution Transformer Terminal Unit is gathered the public electric parameters that becomes and specially become of distribution line, through the GPRS communication network electrical data is sent to the main website server; Timed sending integral point service data (sending once on per 15 minutes), the main website server inserts the PI database with data in real time.According to the power data (general power, total active power, total reactive power, power factor (PF) etc.) of the total circuit that receives, electric degree data (active electrical degree, idle electric degree); The power data of each distribution transforming (general power, total active power, total reactive power, power factor (PF) etc.), electric degree data (active electrical degree, idle electric degree); And voltage, the current data of total circuit and each distribution transforming, calculate the total-power loss on the circuit, total active power loss, total reactive power loss, total active electrical degree loss, total idle electric degree loss; Data after handling are kept in the PI database.Data with after data that receive and the processing generate electric weight form, line loss form, active power form, reactive power form in the measurement period automatically, and can print and derived data.
More than be merely the specific embodiment of the utility model, but the technical characterictic of the utility model is not limited thereto.Any is the basis with the utility model, for realizing essentially identical technique effect, has done the ground simple change, has been equal to replacement or modification etc., all is covered by among the protection domain of the utility model.
