Abstract

A protection and control system which is capable of surely updating a program without a program update by an operator and without deactivating a power system is provided. A protection and control device 1 includes an update accepting unit 1c that determines whether or not to accept the update of the program from a managing server 3, and an updating processing unit 1d that receives an updating program and that updates the program. The managing server 3 includes an update determining unit 3c that determines whether or not a supplied update program is for updating the program of the predetermined protection and control device 1, a transmitting unit 3b that transmits an update notification to the protection and control device 1 on which the program to be updated is loaded, and a receiving unit 3a that receives a reply to the update notification from the protection and control device.

Claims

1. A protection and control system comprising:

a protection and control device that comprises an input-output unit which monitors a voltage or a current of a power system and which controls a switch installed in the power system, a storing unit including a memory that stores a program and update information of the program, and a transmission control unit connected to a communication network; and

a managing server including a hardware processor that transmits a necessity of an update of the program and an updating program to the protection and control device via the communication network,

wherein the protection and control device further comprises;

an update accepting unit that determines whether or not to accept the update of the program transmitted from the managing server; and

an updating processing unit which receives the updating program and which updates the program,

wherein the managing server comprises;

an update determining unit that determines whether or not a supplied update program for updating the program of the predetermined protection and control device;

a transmitting unit that transmits an update notification to the protection and control device on which the program to be updated is loaded;

a receiving unit that receives a reply to the update notification from the protection and control device;

an email processing unit; and

an email information storing unit including a memory that is necessary to transmit and receive an email,

wherein the email processing unit notifies a user'"'"'s external device connected to the communication network of the program to be updated via the communication network when the program on the managing server has been updated,

wherein when the update determining unit determines that the program on the managing server has been updated and the update accepting unit accepts the update of the program of the protection and control device,

the updating processing unit updates the program of the protection and control device when an email processing unit installed in the user'"'"'s external device connected to the communication network gives a command to update the program to the protection and control device.

2. The protection and control system according to claim 1, wherein the managing server comprises the update determining unit that transmits the necessity of the update of the program and the updating program to the protection and control device when the program on the managing server has been updated.

3. The protection and control system according to claim 1, wherein the protection and control device comprises the update accepting unit that determines the necessity of the update of the program, and the update accepting unit transmits automatic update acceptance info'"'"' ration indicating that update is unabled to the managing server.

4. The protection and control system according to claim 1, wherein the managing server further comprises an update control unit that controls a plurality of the protection and control devices in conjunction with each other so as to avoid a simultaneous update when the plurality of the protection and control devices update the respective programs.

5. The protection and control system according to claim 1, wherein the email processing unit transmits an email indicating that the update of the program of the protection and control device is completed to the user'"'"'s external device connected to the communication network.

6. The protection and control system according to claim 5, allowing the external device connected to the communication network which is owned by the user registered in the managing server in advance to check an initial status of the program of the protection and control device and a present status thereof.

7. The protection and control system according to claim 1, allowing an external device connected to the communication network which is owned by the user registered in the managing server in advance to check a status of a trip lock of the protection and control device.

8. The protection and control system according to claim 1, wherein when the update determining unit determines that the program on the managing server has been updated and the update accepting unit accepts the update of the program of the protection and control device,

the protection and control device updates the program when a command to update the program is given to a switch provided on a panel of the protection and control device.
