Description
Technical Field
The invention relates to the technical field of substation telecontrol, in particular to a substation telecontrol communication control method.
Background
With the development of economy, social progress, improvement of science and technology and informatization level and increasingly prominent global resource and environmental problems, the development of power grids faces new subjects and new challenges. The development of power grid dispatching automation, adaptation to the requirements of future sustainable development, and the development of power grid dispatching automation have become a common choice for the international power industry to actively respond to future challenges. The power system dispatching automation is one of the fastest developing technical fields in the current power system, and the main functions of the power system dispatching automation are as follows: data acquisition and monitoring of the power system: the method comprises the following steps of economic operation and scheduling of a power system, marketized operation and reliable operation of power, operation decision support of a power plant and the like; and (4) comprehensive automation of the transformer substation.
The telecontrol system is the basis of the power grid dispatching automation system, and the power grid dispatching center can timely acquire the operation information of the plant station through the telecontrol system; meanwhile, the dispatching center transmits remote control and remote regulation commands to a power plant and a transformer substation through a telemechanical system, and safe, high-quality and economic operation of the power grid is implemented. The application of the telecontrol system in the railway electrified telecontrol system is earlier, and the telecontrol system plays a great role in ensuring the safe and reliable power supply of the electrified railway and improving the dispatching management level of railway transportation. In the development process of the railway electrification system, with the development of computers, different telecontrol system products are provided at different periods, and simultaneously, a large number of telecontrol system products and equipment are introduced from abroad in China, which drive the railway electrification telecontrol system to develop to a higher target.
Telemechanical information is divided into two categories according to different information transmission modes: a round robin approach and a query approach. The transmission mode of the circulating telemechanical information requires that a transmitting end and a receiving end always keep strict synchronization, and information is arranged according to a predetermined sequence and is sequentially and circularly transmitted. The early telecontrol devices are one-to-one, that is, each station is equipped with one set, half set is placed at the transmitting end, half set is placed at the information receiving end (dispatching station), the transmitting and receiving of information are all one-to-one correspondence, and the station end transmits the information in groups according to the time sequence. And after all the remote signaling information is sent, sequentially sending the remote sensing information, completing sending one frame of information after sending the remote sensing information once, and then sending a new frame of information, wherein the steps are repeated. The receiving end (scheduling station) receives the information in a circulating way according to the information sequence agreed in advance. The inquiry mode is mainly that the dispatching end sends out inquiry command, the controlled end works according to the sent command, and the inquired station transmits data or state information to the dispatching end. In the cyclic transmission mode, each station transmits information to the scheduling end in a cyclic manner all the time, so that the transmission period is short. Meanwhile, one station can send information to several places at the same time, and one-shot multi-shot can be achieved. But it has the disadvantages of not flexible enough and large investment, so it is only suitable for radiation type communication network, and the channel utilization rate is low. In the query mode, the scheduling end needs to query the controlled ends one by one, and the efficiency is low.
Disclosure of Invention
In order to solve the problems, the invention provides a substation telecontrol communication control method.
The technical scheme of the invention is as follows:
a substation telecontrol communication control method comprises
S1: the dispatching end remote control device sends request information to the plant station end remote control device;
s2: the plant station end receives the request information and sends the information to the dispatching end telecontrol device;
s3: setting time T, if the station end does not receive the request information in the time period T, actively sending information to a plurality of scheduling ends;
s4: and the staff maintains the equipment according to the equipment fault information.
The information sent by the station terminal comprises voltage, current, power, frequency and electrical degree.
After step S1, if the scheduling-side remote control device 2 does not receive the power data sent by the plant-side remote control device 1 within the time T1, the scheduling-side remote control device 2 sends the request information to the intelligent terminal of the plant-side worker, the worker checks the plant-side remote control device 1, if a fault occurs, the worker checks the current data of the plant-side remote control device 1, and sends the current data (power data) and the fault code to the scheduling-side remote control device through the intelligent terminal.
In step S3, the information received by the plurality of scheduling end remote control devices includes power information and a forwarding identifier, after the plurality of scheduling end remote control devices receive the power information and the forwarding identifier of a certain plant end remote control device, each scheduling end remote control device forwards all the information to the master control center, and if the master control center determines whether the power information sent by each scheduling end remote control device is consistent.
If the power information is consistent, the unified power information is used as real information sent by the plant station end telecontrol device, and at the moment, the master control center sends fault information to a worker of the fault scheduling end telecontrol device; and the master control center judges that the electric power information sent by each dispatching end telecontrol device is inconsistent, sends the return identification code to the station end telecontrol device and simultaneously sends the return identification code to the intelligent terminal of the station end worker.
Compared with the prior art, the invention has the technical effect that the dispatching end actively and sequentially calls the information of each station in sequence. As a station end, the station can send out the information of the station only when the station receives the 'call' of the dispatching end. The mode is flexible, and various types of information can be treated differently. The method is characterized in that the dispatching end issues a command and the plant station end executes the command, so that the function combination can be flexibly changed without changing the plant station end, the method is also suitable for communication networks of any forms, a plurality of plant station ends can be connected on one transmission channel, and the channel investment is saved. Meanwhile, time T is set, and when the request information is not received in the time period T, the information is actively sent to the multiple scheduling terminals, so that the fault information can be found in time.
