Abstract: The power industry is an important economic and social development of basic industries. The rapid development of power industry, effectively supporting the economic and social development. With the growing demand for electricity, power transmission technology continues to evolve. Network security increasingly valued, energy saving growing concern, the ongoing adjustment of the power structure, another new power facilities, the old equipment is constantly updating and transformation, of the increasingly widespread Application of new technologies, so how to enhance the power scheduling and management has become we are concerned with the topic.


In recent years, as technology continues to develop, power dispatch system, has become an important modern monitoring, control and management tools, while it is also the process of social development plays an irreplaceable role. Therefore, in order to enhance the power scheduling and management, we must first understand its content and functionality for its content and functionality the corresponding solutions.

Power dispatch of the basic content, including:
① data collection
Collection points by the end of RTU (OR substation electrical power parameters, including switch location, protection signal, such as voltage and current telemetry data.

② Transfer Information
The RTU collected through reliable channels of Information sent to the master system (front-end server, and transmit control commands issued by the master to the war.

③ Data Processing
The Information collected should be treated, filtered, calculation.

④ human contact
The Information will be processed through a friendly interface presented to the user, and to achieve remote control, remote adjustment function.

Power dispatch system and its functions in the following areas:
① real-time monitoring the quality of power supply system voltage
② real-time monitoring harmonic voltage components
③ on the supply voltage, harmonics and sub-points for the whole time-line monitoring and collection system power system power supply voltage quality, harmonic voltage components and power loss of time, timely and accurate voltage quality management to a dedicated team to provide operational data.

For the above mentioned content and its function, we have proposed a technology for power dispatch planning objectives.

A safe and stable grid operation and control
1.1 implementation of national energy policy and the implementation of electric power development strategy, full use of grid resources and power resources to meet the electricity market environment, the national power resources to achieve optimal scheduling.

1.2 to adapt to the requirements of network development, a reasonable division of power control area, an advanced Internet network frequency and tie-line control mode, to develop appropriate regulations and standards.

1.3 to improve network security analysis and operational control level, try the 500 kV, 330 kV system does not place the main responsibility for the stability of the scheduled destruction of the system collapse and other accidents.

1.4 according to the specific circumstances of the grid, configuration, advanced technology, safe and reliable security and stability control, continue to develop the security and stability control technology.

2 Electricity Market Operation
2.1 of master-level, regional level and the provincial electricity market operating technologies, municipalities, three of the electricity market operation.

2.2 Research and development, timely establishment of a sound commercial power generation side of the electricity market support systems to achieve quote processing, trading schemes, security checking, congestion management, ancillary services, assessment billing, contract management, market forecasting, Information dissemination and offer aid decision-making functions to protect the power generation side of electricity markets fair and orderly operation.

2.3 to carry out marketing and sale of electricity transmission market operations Research.

2.4 All above the provincial level to carry out the electricity market operator shall be put into operation in the electricity market technical support system.

3 dispatching automation
3.1 perfect state transfer, the net transfer, provincial transfer EMS system interconnection and data exchange.

3.2 national network of provincial transfer all of the AGC function to achieve practical and suitable for large area power grid interconnection and power market requirements, the frequency of quality reach the international advanced level.

3.3 full Application of provincial transfer network load forecasting, state estimation, dispatcher trend, static security analysis, DTS and other Application software, developed by the experience-based scheduling to analytical, intelligent scheduling.

3.4 full use of existing state power data network (SPDEND, gradually improve the scheduling system scheduling real-time control of power dedicated data network, connecting all levels of the dispatch center and the direct dispatch of power plants and substations, improve the national network, improved built in all Region two networks, 90 percent of the province into three networks. in accordance with the requirements of national security, we must realize that the public Internet network and the external and internal public power information network security isolation, real-time control systems to ensure safe and reliable. turn affixed to the free download http://www.hi138.com 3.5 continue to improve production scheduling management system, make the country tune, the net transfer, provincial transfer three scheduling and production management systems and mutual visits.

Although the goal is clear, but because of the power to improve the place, "Eleventh Five-Year" period should be separated from transmission and distribution reform work is not progress, is still a high degree of monopoly power grid company in the performance of basic social responsibility, the pursuit of additional profits its nature as a monopoly. under the power grid operator company, consciously or unconsciously, to become power companies to achieve strategic objectives of business tools, making the role of its schedule between the functions of public administration has gone wrong.

Power system of the objective requirements of the law of supply and demand to maintain the instantaneous physical balance, but because of the physical characteristics of the unit constraints, network congestion constraints and load fluctuations, uncertainties and other hydrological factors, particularly in the power system failures and other unexpected events, power supply and demand balance will be broken at any time, and may endanger the power system security and stability.

4 for the power system in a series of questions, the following measures should be taken
4.1 strengthen their leadership and responsibility, adhere to the "number one hand grasping the first productive force." Schedule planning at all levels of technological development at all levels of grid technology is an important part of development planning, the number one overall charge of the dispatch center, Chief Engineer is responsible for organizing. Application of scientific and technological achievements into the scheduling system compliance rate of first-class scope of examination, and as a scheduling central leadership of the examination content.

4.2 investments in technology, science and technology to ensure an annual cost of the project implementation, and focus on scheduling the production of much-needed major technical problems.

4.3 actively promote the dispatching system equipment in China, may be the introduction and assimilation of advanced technological innovations, Applications with independent intellectual property rights advocate, in line with the actual Chinese power grid technologies and products.

4.4 The construction project scheduling system under the same conditions give priority to domestic equipment and systems to support the national industry, but does not protect the backward, through fair competition, to promote the industry's technological progress.

4.5 establish and improve the technical standards, and actively adopt international standards, the absorption of foreign advanced standards, establish and improve the standardization of application systems, dispatching systems to achieve the technical standards with international standards.

4.6 to strengthen personnel training, to ensure the quality and number of personnel professionals in the safe operation of power grids to meet the needs to attract attention to master high-tech personnel, planned training of existing staff, to develop training standards, proposed to set staffing levels and scheduling professional staff qualifications standards. Regular training of professionals (including overseas training, organizational and technical personnel from time to time to the advanced power company (company to investigate the technical measures and management methods.

4.7 to encourage engineering innovation and management innovation, every two years, named in recognition of "outstanding contributions to the national grid scheduling system expert."
4.8 pairs of dispatching system needed to solve technical problems, the organization of joint Research in each unit will focus on a voluntary basis, the appropriate division of the project, to ensure timely completion.

4.9 to develop the annual plan, periodic inspection with held every two years, "China Power Dispatching meeting", we held dispatching systems technology conference, check the completion of the project, to discuss the new Research.

Described above with power dispatch-related measures, the measures only a small part, will have to be implemented according to specific conditions and therefore, in order to improve the national level, grasp the power dispatch is especially important with the science and technology development, the economy continues to improve, for all kinds of things happen, we will have a better response.
