Description

  The present invention relates to a remote monitoring operation system for remotely monitoring or operating one or both of the operation state monitoring and the operation operation of monogeneration systems or cogeneration system power generation facilities in a plurality of scattered bases.

  In recent years, fossil fuel input type distributed power sources of various scales have been commercialized, and on-site power supply by monogeneration and cogeneration (fossil fuel input type private power generation facilities) in conjunction with expansion of self-development agency services However, it is spreading mainly in manufacturing and stores. In addition, as part of the energy conservation policy, in order to promote the ESCO (Energy Service Company) business that provides comprehensive energy conservation services for office buildings, factories, etc., the establishment of business recognition such as the proactive introduction in the public sector Active use has been promoted.

  However, the operation and maintenance of such power generation facilities requires deep knowledge and know-how regarding electricity theory, prime movers, and generators, and it is difficult for users of power generation facilities themselves to operate and maintain power generation facilities. As a result, there are many cases in which power generation equipment maintenance work is outsourced to prime movers and generator manufacturers, and the market for power generation equipment maintenance business is increasing.

  Conventionally, maintenance work for power generation facilities has been mainly performed by maintenance personnel who conduct periodic inspections and perform operation and maintenance. However, as the number and areas of power generation facilities subject to maintenance expand, maintenance personnel are proportionate to that. It is necessary to increase the number of employees, and the economy is impaired.

  Therefore, in order to efficiently and economically promote the maintenance work of a large number of power generation facilities over a wide range of areas, an operation state monitoring device for monogeneration systems or cogeneration system power generation facilities in a plurality of scattered bases is installed. There is a tendency to reduce the number of maintenance personnel by constructing a remote monitoring system remotely from a remote management center or the like and efficiently performing integrated monitoring.

According to such a flow, Patent Document 1 is known as a publicly known document relating to a remote monitoring system of a cogeneration system.
JP 2003-131730 A

  The construction of a remote monitoring system requires a communication line for transmitting and receiving monitoring data. However, in the remote monitoring system described in the above-mentioned publicly known document, it is common to use a public telephone line for the communication line. .

  However, in data communication by a circuit switching method using a general public telephone line, only data communication between two points connected to the line can be performed. In order to realize simultaneous monitoring of the same power generation equipment from the apparatus, a large number of lines are required on the management center side and the power generation equipment side, and the communication cost also increases.

  In addition, if you try to acquire a large amount of monitoring data for advanced monitoring, there is an economic problem such as an increase in communication costs due to a pay-as-you-go system, and the problem that simultaneous data communication is possible only for the number of lines. There is. Since line connection / switching operations are required to perform data communication, there are various operational problems such as complicating data communication processing and impairing the immediacy of monitoring for the time required for line connection / switching.

  In order to solve these problems, it is possible to realize high-quality data communication by using a dedicated line for a flat rate and always-on connection, but various costs such as line usage fee for communication become high. In view of this, it cannot be said to be a practical solution. In addition, when a general public telephone line or a dedicated line is used as a communication line, it is difficult to realize remote monitoring of power generation facilities such as a ship overseas or sailing because of the limited coverage area of the communication line.

  In addition, the maintenance system of the main after-sales service, which recovers the failure after the failure of the power generation facility, has been removed. For example, the operation status of the power generation facility is monitored to show signs of the power generation facility failure. Detecting and dealing with this problem prevents power failures and improves power generation economics through predictive maintenance that reduces the economic loss of power generation equipment users by stopping power generation equipment and long-term monitoring of power generation equipment operating conditions Even if you try to build a maintenance system that includes a before service that brings greater benefits to power generation equipment users, such as high-efficiency operation that derives the optimal operation pattern of the power generation equipment to be generated and performs optimal power generation control based on it As described in the literature, this is a remote monitoring system that can only perform remote monitoring and cannot perform remote operations. For example, when predictive maintenance is used to detect signs of power generation equipment failure and prevent any failure, the power generation equipment must be operated in some way, or to generate more efficient power generation. Even when setting values related to controller power generation control are changed, maintenance personnel need to visit the power generation facility each time, and considering the large-scale maintenance system necessary to make this possible, the economics of maintenance and From the viewpoint of efficiency, it is difficult to establish a maintenance system including before service.

  Furthermore, in the monitoring system mainly of the management center, such as the remote monitoring system described in the above-mentioned publicly known literature, it is necessary for the active maintenance staff to contact the management center every time in order to grasp the operating state of the power generation equipment in charge. In addition, in order to enable the operation of a lubricous maintenance service, it is necessary to increase the number of monitoring operator operators in the management center and to establish a 24-hour monitoring system. There is a problem such as it takes time to collect initial information.

  The present invention has been made to cope with such a situation, and its problem is to solve various problems in the conventional remote monitoring system, and to improve the maintenance system including not only after-sales service but also before-sales service. The object is to provide a remote monitoring operation system necessary for constructing with a simple method that saves labor and cost as much as possible.
